Available in PDF, EPUB and Kindle. Book excerpt: The conserved vector current theory predicts that the branching ratio for the decay of a charged pion into a neutral pion is (1.05=0.02)x10 to the -8th power, if the coupling constant is derived from muon decay, or (1.00=0.02)x10 to the -8th power, if the coupling constant is derived from nuclear beta decay. Using spark chambers to distinguish the nearly anticollinear gamma rays from pi(+) beta decay from a background of other gamma rays, we have found 36 events and have measured the branching ratio to be (0.97=0.20)x10 to the -8th power, in agreement with the theoretical prediction and previous measurements. The method of background subtraction (approximately 10%) depends only on knowing that the background is isotropic for gamma rays having opening angles between 160 degrees and 180 degrees. (Author).

Download or read book High Energy Physics written by Glenn Cunningham and published by Scientific e-Resources. This book was released on 2019-07-07 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word "e;particle"e; can refer to various types of very small objects "e;particle physics"e; usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behaviour. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "e;known"e; particle, the Higgs boson, or even to the oldest known force field, gravity. Written in a clear pedagogic style by active researchers, this book will prepare a beginner to work in the field and at the same time will also provide useful reference material for active researchers.

This book was released on 2004-08-12 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research with radioactive ion beams has entered a new era with the advent of energetic beams of radioactive nuclei able to induce nuclear reactions. The present book is the first volume of edited lectures based on material presented at the Euroschool on Exotic Beams over the past years. It introduces the graduate student and nonspecialist scientist from related areas to various topics encompassing theoretical, experimental as well as application-related aspects of this growing field of research.

This book was released on 2007-05-11 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume is a collection of reviews, essays and personal reminiscences on Occhialini's scientific life and work. Through these recollections the reader will also gain a vivid impression of the pioneering days of elementary particle physics when new detection methods emerged, like the triggered cloud chamber and nuclear emulsions - two techniques perfected by Occhialini - which made progress on comic ray physics possible in the first place.
Download or read book On the Origin of Natural Constants written by Hans Peter Good and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-10-22 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just as the circle number π or the Euler constant e determines mathematics, fundamental constants of nature define the scales of the natural sciences. This book presents a new perspective by means of a few axioms and compares the resulting validity with experimental data. By the axiomatic approach Sommerfeld's mysterious fine-structure constant and Dirac's cosmic number are fixed as pure number constants. Thanks to these number constants, it is possible to calculate the value for the anomalous magnetic-moment of the electron in a simple way compared to QED calculations. With the same number constants it is also possible to calculate masses, partial lifetimes, magnetic-moments or charge radii of fundamental particles. The expressions used for the calculations, with few exceptions, yield values within the experimental error limits of the Particle Data Group. The author shows that the introduced number constants give even better predictions than the complicated QED calculations of today's doctrine. In the first part only experimental data from the literature for checking the postulates are used. In the second part the author explains electrical transport measurements with emergent behaviour, which were carried out in a professional environment.

This book was released on 1995-05-31 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of hadronic and nuclear probes with protons and electrons in the energy range of a few GeV is of great importance for the understanding of the properties of nucleons and mesons as well as of their interaction. Experimental results from studies with these beams provide the basis for the development and the tests of theoretical approaches in the energy regime of non-perturbative QCD. They can also clarify the effect of the nuclear medium on elementary reactions. The conference has reviewed the present status of this field of research. The topics have beenThe conference topics comprised investigations near energy thresholds in the tradition of the conferences on Particle Production near Threshold in Nashville, IN, USA, 1990, and Uppsala, Sweden, 1992.
Download or read book Fundamentals Of Electroweak Theory Second Edition written by Jiri Horejsi and published by World Scientific. This book was released on 2024-06-11 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the lecture course taught by the author for about three decades at Charles University. The author gives a thorough and easy-to-read account of the basic principles of the standard model of electroweak interactions, describes various theories of electromagnetic and weak interactions, and explains the gauge theory of electroweak interactions. The criterion of the tree-level unitarity is used throughout the text to check the gradual steps leading to the renormalizable electroweak theory. Five appendices expound on some special techniques of the Standard Model, used in the main body of the text.The book can be read with just a preliminary knowledge of quantum field theory. In comparison with the first edition of the book published more than 20 years ago, new passages concerning the Higgs boson are added, as well as some new problems and solutions.
