Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Summer Institute 1978 was held at Karlsruhe from Sept. 4 to Sept. 16. The title of the school "New Phenomena in Lepton and Hadron Physics" relates to the present very exciting phase in particle physics. An impressive amount of experimental data has been collected in support of a fundamental new picture of the subnuclear world, - a picture which has found its theoretical formulation in Que~tum Chromodynamics and Gau~ theories. It is a general philosophy of the ASI to address the courses mainly to young and learning scientists, hence our major objective was to offer systematic reviews of both, the experimental situa tion and the basic theoretical concepts of the field. This volume contains the written versions of the major lectures delivered during the course. In addition several lectures and seminars had been scheduled in which also more original and specialized subjects were discus sed by invited speakers and participants of the school. Not all of these contributions are contained in this book.

This book was released on 2016-09-26 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Dorigo provides an engaging and insightful perspective on the pursuit of physics discoveries at CDF … Dorigo’s book is thus almost certainly going to be an important source for anyone interested in the history of CDF … It is a personal yet highly informative story of discovery and almost-discovery from the perspective of someone who saw the events firsthand.'Physics TodayFrom the mid-1980s, an international collaboration of 600 physicists embarked on the investigation of subnuclear physics at the high-energy frontier. As well as discovering the top quark, the heaviest elementary particle ever observed, the physicists analyzed their data to seek signals of new physics which could revolutionize our understanding of nature.Anomaly! tells the story of that quest, and focuses specifically on the finding of several unexplained effects which were unearthed in the process. These anomalies proved highly controversial within the large team: to some collaborators they called for immediate publication, while to others their divulgation threatened to jeopardize the reputation of the experiment.Written in a confidential, narrative style, this book looks at the sociology of a large scientific collaboration, providing insight in the relationships between top physicists at the turn of the millennium. The stories offer an insider's view of the life cycle of the 'failed' discoveries that unavoidably accompany even the greatest endeavors in modern particle physics.

This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents two searches for phenomena beyond the Standard Model using events with three or more charged leptons. The searches are based on 20.3 fb-1 of proton- proton collision data with a center-of-mass energy of √s = 8 TeV collected by the ATLAS detector at the CERN Large Hadron Collider in 2012. The first is a model-independent search for excesses beyond Standard Model expectations in many signal regions. The events are required to have least three charged leptons, of which at least two are electrons or muons, and at most one is a hadronically decaying [tau] lepton. The selected events are categorized based on the flavor and charge of the leptons, and the signal regions are defined using several kinematic variables sensitive to beyond the Standard Model phenomena. The second search looks for new heavy leptons decaying resonantly to three electrons or muons, two of which are produced through an intermediate Z boson. The resonant decay produces a narrowly- peaked excess in the trilepton mass spectrum. In both cases, no significant excess beyond Standard Model expectations is observed, and the data are used to set limits on models of new physics. The model-independent trilepton search is used to confront a model of doubly charged scalar particles decaying to e[tau] or [mu][tau], excluding masses below 400 GeV at 95% confidence level. The trilepton resonance search is used to test models of vector-like leptons and the type III neutrino seesaw mechanism. The vector-like lepton model is excluded for most of the mass range 114 GeV - 176 GeV, while the type III seesaw model is excluded for most the mass range 100 GeV - 468 GeV. Both searches also present tools to facilitate reinterpretations in the context of other models predicting the production of three or more charged leptons.

Available in PDF, EPUB and Kindle. Book excerpt: Physicists actively engaged in advanced research should be en couraged to discuss results and deepen their theoretical understand ing of the data. It is practically impossible nowadays to achieve the goal of the old times when small groups of scientists had the privilege of debating their ideas and the details of their experi ments in an informal and friendly way. Conferences are now too wide in scientific coverage and, in consequence, there are often too many participants. The Highly Specialized Seminars of the Ettore Majorana Centre for Scientific Culture are intended to provide such a forum for scientists of outstanding reputation in their fields to exchange information. This volume deals with one of the most interesting topics in subnuclear physics, and Professor Giuliano Preparata is one of the world's leaders in the field. This volume contains the most recent results on the study of deep inelastic phenomena, using neutrinos, muons and electrons against nucleons, and (e+e- ) interactions. It represents our best knowledge of the field as given by some of the most distinguished world experts in the theoretical and experimental domain. Antonino Zichichi, Director Ettore Majorana Centre for Scientific Culture v PREFACE In March 1979, about 50 physicists gathered in Erice to parti cipate in the Fourth Highly Specialized Seminar on "Probing Hadrons with Leptons."
Download or read book Hadron models and related New Energy issues written by Florentin Smarandache and published by Infinite Study. This book was released on 2007-01-01 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book covers a wide-range of issues from alternative hadron models to their likely implications to New Energy research, including alternative interpretation of low-energy reaction (coldfusion) phenomena.The authors explored some new approaches to describe novel phenomena in particle physics. M Pitkanen introduces his nuclear string hypothesis derived from his Topological Geometrodynamics theory, while E. Goldfain discusses a number of nonlinear dynamics methods, including bifurcation, pattern formation (complex Ginzburg-Landau equation) to describe elementary particle masses. Fu Yuhua discusses a plausible method for prediction of phenomena related to New Energy development.F. Smarandache discusses his unmatter hypothesis, and A. Yefremov et al. discuss Yang-Mills field from Quaternion Space Geometry. Diego Rapoport discusses link between Torsion fields and Hadronic Mechanic.A.H. Phillips discusses semiconductor nanodevices, while V. and A. Boju discuss Digital Discrete and Combinatorial methods and their likely implications to New Energy research. Pavel Pintr et al. describe planetary orbit distance from modified Schrodinger equation, and M. Pereira discusses his new Hypergeometrical description of Standard Model of elementary particles.The present volume will be suitable for researchers interested in New Energy issues, in particular their link with alternative hadron models and interpretation.While some of these discussions may be found a bit too theoretical, our view is that once these phenomena can be put into rigorous theoretical framework, thereafter more 'open-minded' physicists may be more ready to consider these New Energy methods more seriously. Our basic proposition in the present book is that considering these new theoretical insights, one can expect there are new methods to generate New Energy technologies which are clearly within reach of human knowledge in the coming years.

Available in PDF, EPUB and Kindle. Book excerpt: During July 1990. a group of 83 physicists from 43 laboratories in 21 countries met in Erice for the 28th Course of the International School of Subnuclear Physics. The countries represented were: Algeria. Canada. Chile. China. Czechoslovakia. Denmark. France. the Federal Republic of Germany. Greece. Holland. India. Italy. Pakistan. Peru. Poland. Sweden. Switzerland. Turkey. the Union of Soviet Socialist Republics. the United Kingdom. and the United States of America. The School was sponsored by the European Physical Society (EPS). the Italian Ministry of Education (MPI). the Italian Ministry of University and Scientific Research. the Sicilian Regional Government (ERS). and the Weizmann Institute of Science. The new topic discussed in some detail at the School was QCD phenomenology at 200 TeV. This energy frontier represents the goal for subnuclear physics after LHC and sse. The main lecturers were T.D. Lee. L. Cifarelli. Y. Dokshitzer and A. Ringwald. There are two possibilities. one optimistic. the other pessimistic. LHC and SSC can produce remarkable discoveries. In this case. the need to go to higher energies will be obvious. In the pessimistic case. LHC and SSC will produce the strongest evidence for the validity of the Standard Model. The need for higher energies will be impelled. In neither case can we wait. If the 200 TeV frontier is to be reached within our lifetime we need to start now: thinking and preparing the tools. Theory and R&D for future detectors are the basic points of the 200 TeV frontier.

This book was released on 2012-12-06 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the Proceedings of a Europhysics Study Conference held in Erice, Sicily from March 17 to 24, 1980. The objective of the meeting was to bring together practitioners of two different approaches to the unification of the fundamental par ticle interactions: supersymmetry and supergravity on the one hand, and grand unified gauge theories on the other hand. The hope was that exposure to each others' ideas and problems would at least aid mutual comprehension, and might start people thinking how to develop a synthesis of the two approaches which could avoid their individual shortcomings. It is not clear to us how successful the conference was in achieving these objectives. On the one hand many important ad vances in supersymmetric theories were reported which were primarily of a technical nature, while some interesting attempts to probe the phenomenological consequences of supersymmetry and supergravity were also presented. On the other hand there was considerable in terest in phenomenological aspects of grand unified theories such as proton decay, neutrino masses and oscillations, and links with cosmology. There was also some work on model-building but rela tively few purely technical advances. A few speakers tried to build bridges between the formalism of supersymmetry or supergravity and the phenomenologically successful gauge theories of elementary par ticle interactions.

Available in PDF, EPUB and Kindle. Book excerpt: During August 1980 a group of 85 physicists from 57 laboratories in 21 countries met in Erice for the 18th Course of the International School of Subnuclear Physics. The countries represented were Argentina, Austria, Belgium, Bulgaria, Canada, China, Colombia, Czechoslovakia, the Federal Republic of Germany, France, Hungary, Israel, Italy, Japan, the Netherlands, Poland, Spain, Switzerland, the United Kingdom, the United States of America, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MFI) , the Italian Ministry of Scientific and Technological Research (MRST) , the Regional Sicilian Government (ERS), and the Weizmann Institute of Science. The programme of the School was mainly devoted to a review of the very low energy corner where we are all working at present, and to a discussion of what the future could be for subnuclear physics before the end of this century. On the theoretical front, the highlight of this Course was the lectures by S. Adler on the non-local U(2) gauge theory. The non locality at the colour-level should disappear at the colour-singlet level -- where all particles we know of exist and should the- fore not scare those who do not like the idea of giving up this basic principle of quantum field theory: locality. On the other hand, the great dream of producing the world where we live, starting from the simplest symmetry group U(2), now seems to have a good chance of becoming a reality.

Available in PDF, EPUB and Kindle. Book excerpt: In August 1982 a group of 104 physicists from 70 laboratories of 31 countries met in Erice to attend the 20th Course of the Inter national School of Subnuclear Physics. The countries represented at the School were: Argentina, Australia, Austria, Belgium, Brazil, Bulgaria, Canada, Chile, China, Czechoslovakia, France, the Federal Republic of Germany, Greece, India, Iran, Israel, Italy, Japan, Morocco, the Netherlands, Norway, Poland, South Africa, Spain, Sweden, Switzerland, Turkey, the United Kingdom, the United States of America, Yugoslavia, and Zimbabwe. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Techno- logical Research (MRSI), the Sicilian Regional Government, and the Weizmann Institute of Science. This year, on the occasion of the 60th birthday of Chen Ning Yang, the "Ettore Majorana" Centre decided to pay tribute to the outstanding scientific achievements of one of the most prominent scientists of our time, by dedicating the 20th Course of the International School of Subnuclear Physics to a review of the pre sent status of one of the fields of physics where Chen Ning Yang has contributed most profoundly: gauge interactions. The theo retical foundations and the most recent developments were presented by Chen Ning Yang. The most general consequences of a gauge inter action -- supersymmetry -- with its theoretical aspects and the experimental implications were discussed by Sergio Ferrara and Demetrios Nanopoulos.

Book excerpt: In August 1979 a group of 94 physicists from 60 laboratories in 21 countries met in Erice to attend the 17th Course of the International School of Subnuclear Physics. The countries represented at the School were: Argentina, Australia, Austria, Belgium, Canada, Federal Republic of Germany, France, Hungary, India, Italy, Japan, Korea, the Netherlands, Nor way, Poland, Rumania, Spain, Sweden, the United Kingdom, the United States of America, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Techno logical Research (MRST) , the Sicilian Regional Government, and the Weizman Institute of Science. In the theoretical sessions, as expected, Sidney Coleman's (liN) lectures provided a new masterpiece in his Erice series. Andre Martin lectured on the theory of new particles, R.L. Jaffe on the Bag Hodel and Francis E. Low on quark status at low energy. In the more specialized section we were able to reflect on the problem of asymptotic changes in gauge theory, troubles experienced with instantons and finally on the fate of false vacua, thanks to A. Patrascioiu, R. Petronzio, and H. Kleinert. A quite exceptional event this year was the special QCD session wId_ch I leave the reader to enjoy without further introduction.

This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the written versions of the lectures held at the "22 Internationale Universitatswochen fur Kern physik" in Schladming, Austria, in February 1983. The generous support of the Austrian Federal Ministry of Science and Research, the Styrian Government and other sponsors once again made it possible for expert lecturers to be invited. In choosing the topics, the aim was to achieve a balance between the theoretical and phenomenological contributions; on the theoretical side, discussions centred on the impact of different approaches to quantum field theory on the ele mentary particle scenario, on the other, on the recent re sults in high energy physics which have provided fresh moti vations for new kinds of experiments as well as having had a profound influehce on cosmology. Limited space has made it impossible to include manuscripts of the many interesting seminars presented. The lecture notes were reexamined by the authors after the school and are now published in their final form. It is a pleasure to thank all the lecturers for their efforts, which made it possible to speed up publication. Thanks are also due to Mrs. Neuhold for the careful typing of the notes. H. Mitter C.B.
