Download or read book Inferred Limits on Lepton Flavor Violating Decays of the Ks written by and published by . This book was released on 2005 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strong model independent upper bounds on Br(K{sub s} →?° e?) may be inferred from recent experimental limits on Br(K{sub L} →?° e?) and Br(K →?+e+?−). From this result, upper bounds for Br(K{sub s} → e?) may be obtained for a broad class of models. Models outside of this class seem unlikely.

Available in PDF, EPUB and Kindle. Book excerpt: Charged lepton-flavor violating processes are extremely rare in the Standard Model, but they are predicted to occur in several beyond-the-Standard Model theories, including Supersymmetry or models with leptoquarks or compositeness. We present a search for such processes in a sample of 117 x 106 [Upsilon](3S) decays recorded with the BABAR detector.

Available in PDF, EPUB and Kindle. Book excerpt: This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

It allows for an extremely precise check of the standard model of elementary particles and of its limitations.
Book Synopsis The Physics of Massive Neutrinos by : Boris Kayser
Download or read book The Physics of Massive Neutrinos written by Boris Kayser and published by World Scientific. This book was released on 1989 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the physics and phenomenology of massive neutrinos. The authors argue that neutrino mass is not unlikely and consider briefly the search for evidence of this mass in decay processes before they examine the physics and phenomenology of neutrino oscillation. The physics of Majorana neutrinos (neutrinos which are their own antiparticles) is then discussed. This volume requires of the reader only a knowledge of quantum mechanics and of very elementary quantum field theory.
