Download or read book Measurement of the Top Quark Mass in the Dilepton Final State Using the Matrix Element Method written by Alexander Grohsjean and published by Springer Science & Business Media. This book was released on 2010-10-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main pacemakers of scienti?c research are curiosity, ingenuity, and a pinch of persistence. Equipped with these characteristics a young researcher will be s- cessful in pushing scienti?c discoveries. And there is still a lot to discover and to understand. In the course of understanding the origin and structure of matter it is now known that all matter is made up of six types of quarks. Each of these carry a different mass. But neither are the particular mass values understood nor is it known why elementary particles carry mass at all. One could perhaps accept some small generic mass value for every quark, but nature has decided differently. Two quarks are extremely light, three more have a somewhat typical mass value, but one quark is extremely massive. It is the top quark, the heaviest quark and even the heaviest elementary particle that we know, carrying a mass as large as the mass of three iron nuclei. Even though there exists no explanation of why different particle types carry certain masses, the internal consistency of the currently best theory—the standard model of particle physics—yields a relation between the masses of the top quark, the so-called W boson, and the yet unobserved Higgs particle. Therefore, when one assumes validity of the model, it is even possible to take precise measurements of the top quark mass to predict the mass of the Higgs (and potentially other yet unobserved) particles.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced Material Interfaces is a state-of-the-art look at innovative methodologies and strategies adopted for interfaces and their applications. The 13 chapters are written by eminent researchers not only elaborate complex interfaces fashioned of solids, liquids, and gases, but also ensures cross-disciplinary mixture and blends of physics, chemistry, materials science, engineering and life sciences. Advanced interfaces operate fundamental roles in essentially all integrated devices. It is therefore of the utmost urgency to focus on how newly-discovered fundamental constituents and interfacial progressions can be materialized and used for precise purposes. Interfaces are associated in wide multiplicity of application spectrum from chemical catalysis to drug functions and the advancement is funnelled by fine-tuning of our fundamental understanding of the interface effects.

Download or read book Electroweak Processes in External Electromagnetic Fields written by Alexander Kuznetsov and published by Springer Science & Business Media. This book was released on 2003-10-01 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the intersection of particle physics, astrophysics, and cosmology known as astroparticle physics. Extreme electromagnetic conditions present in puslars and other stars allow for investigations of the role of quantum processes in the dynamics of astrophysical objects and in the early Universe. Based in part on the authors' own work, this book systematically describes several methods of calculation of the effects of strong electromagnetic fields in quantum processes using analytical solutions of the Dirac equation and Feynmann diagrams at both the loop and tree levels. The consideration is emphasized at the two limiting cases: the case of a very strong magnetic field, and the case of a crossed field. The presentation will appeal to graduate students of theoretical physics with prior understanding of Quantum Field Theory (QFT) and the Standard Model of Electroweak Interactions, as well as specialists in QFT wishing to know more about the problems of quantum phenomena in external electomagnetic fields.
Download or read book Physics and Astrophysics of Ultra High Energy Cosmic Rays written by M. Lemoine and published by Springer Science & Business Media. This book was released on 2001-12-14 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International School on Physics and Astrophysics of Ultra High Energy Cosmic Rays (UHECR2000) was held at the Observatoire de Paris–Meudon on June 26-29, 2000. This was the ?rst international school speci?cally dedicated to ultra high energy cosmic rays. Its aim was to familiarize with and attract students, physicists and astronomers into this quickly developing newresearch ?eld. The mysterious and currently unknown origin of the most energetic par- cles observed in Nature has triggered in recent years theoretical speculations ranging from electromagnetic acceleration to as yet undiscovered physics - yond the Standard Model. It has also lead to the development of several new detection concepts and experimental projects, some of which are currently - der construction. By its nature, the ?eld of ultra high energy cosmic rays is therefore highly interdisciplinary and borrows from astrophysics and cosmology, via particle physics, to experimental physics and observational astronomy. One main aspect of the school was to emphasize and take advantage of this interd- ciplinarity. The lectures were grouped into subtopics and are reproduced in this volume in the following order: After a general introductory lecture on cosmic rays follow two contributions on experimental detection techniques, followed by three lectures on acceleration in astrophysical objects. The next four contri- tions cover all major aspects of propagation and interactions of ultra high energy radiation, including speculative issues such as newinteractions.

Available in PDF, EPUB and Kindle. Book excerpt: The pioneering work of Edwin T. Jaynes in the field of statistical physics, quantum optics, and probability theory has had a significant and lasting effect on the study of many physical problems, ranging from fundamental theoretical questions through to practical applications such as optical image restoration. Physics and Probability is a collection of papers in these areas by some of his many colleagues and former students, based largely on lectures given at a symposium celebrating Jaynes' contributions, on the occasion of his seventieth birthday and retirement as Wayman Crow Professor of Physics at Washington University. The collection contains several authoritative overviews of current research on maximum entropy and quantum optics, where Jaynes' work has been particularly influential, as well as reports on a number of related topics. In the concluding paper, Jaynes looks back over his career, and gives encouragement and sound advice to young scientists. All those engaged in research on any of the topics discussed in these papers will find this a useful and fascinating collection, and a fitting tribute to an outstanding and innovative scientist.
Download or read book Top Quark Pair Production written by Anna Christine Henrichs and published by Springer Science & Business Media. This book was released on 2013-10-04 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before any kind of new physics discovery could be made at the LHC, a precise understanding and measurement of the Standard Model of particle physics' processes was necessary. The book provides an introduction to top quark production in the context of the Standard Model and presents two such precise measurements of the production of top quark pairs in proton-proton collisions at a center-of-mass energy of 7 TeV that were observed with the ATLAS Experiment at the LHC. The presented measurements focus on events with one charged lepton, missing transverse energy and jets. Using novel and advanced analysis techniques as well as a good understanding of the detector, they constitute the most precise measurements of the quantity at that time.

Download or read book Ideation Conceptualization Realization written by Sarah Leins-Zurmuehle and published by buch & netz. This book was released on 2021-10-11 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The software industry is regarded as one of the most creative and dynamic industries in the world. At the same time, sheltering software through copyright and patent law has been a major point of contention for the past 40 years. This doctoral thesis aims to provide new insights to this discussion. Through the use of sociological methodology, it supplies the necessary basic scientific reasearch regarding how software is developed and commercialized nowadays. Based on these findings, it then legally evaluates to what extent copyright and patent law are able to reflect these structures and determines how an optimal protection scope for computer programs could look like today. This doctoral thesis on one hand offers novel insights and points of view on existing legal doctrines. It further acknowledges as well as legally qualifies some prevailing trends in the software industry, such as Scrum and continuous delivery, that have so far been largely unaddressed by copyright and patent law.

Download or read book Authority and Authorship in Medieval and Seventeenth Century Women s Visionary Writings written by Deborah Frick and published by transcript Verlag. This book was released on 2021-05-31 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In medieval and early modern times, female visionary writers used the mode of prophecy to voice their concerns and ideas, against the backdrop of cultural restrictions and negative stereotypes. In this book, Deborah Frick analyses medieval visionary writings by Julian of Norwich and Margery Kempe in comparison to seventeenth-century visionary writings by authors such as Anna Trapnel, Mary Carey, Anne Wentworth and Katherine Chidley, in order to investigate how these women authorised themselves in their writings and what topoi they use to find a voice and place of their own. This comparison, furthermore, and the strikingly similar topoi that are used by the female visionaries not only allows to question and examine topics such as authority, authorship, images of voice and body; it also breaks down preconceived and artificial boundaries and definitions.
