Book excerpt: Neutrinoless 3-prong tau lepton decays into a charged lepton and either two all channels the numbers of events found are compatible with background an update of a previous study and the addition of six decay channels. In charged particles or one neutral meson have been searched for using 4.79 fb−1 estimates and branching fraction upper limits are set for 28 different decay modes. These limits are either more stringent than those set previously or of data collected with the CLEO II detector at CESR. This analysis represents represent the first attempt to find these decays.

Available in PDF, EPUB and Kindle. Book excerpt: We have searched for lepton family number violating decays of the[tau] lepton using final states with an electron or a muon and one or more[pi][sup 0] or[eta] mesons but no neutrinos. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.68 fb[sup -1]. No evidence for signals was found, resulting in much improved limits on the branching fractions for the one-meson modes and the first upper limits for the two-meson modes.

Available in PDF, EPUB and Kindle. Book excerpt: The authors search for the neutrinoless, lepton-flavor-violating tau decays?− → l−V°, where l is an electron or muon and V° is a fector meson reconstructed as? → KK−,? →?+?−, K* → K+?−, {bar K}* → K−?+. The analysis has been performed using 451 fb−1 of data collected at an e+e− center-of-mass energy near 10.58 GeV with the BABAR detector at the PEP-II storage rings. The number of events found in the data is compatible with the background expectation, and upper limits on the branching fractions are set in the range (2.6-19) x 10−8 at the 90% confidence level.

Download or read book New Era For Cp Asymmetries Axions And Rare Decays Of Hadrons And Leptons written by Ikaros I Bigi and published by World Scientific. This book was released on 2021-07-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.

Available in PDF, EPUB and Kindle. Book excerpt: A search for the neutrinoless, lepton-flavor violating decay of the [tau] lepton into three charged leptons has been performed using an integrated luminosity of 468 fb−1 collected with the BABAR detector at the PEP-II collider. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (1.8-3.3) x 10−8 at 90% confidence level.

Download or read book A Search for Neutrinoless Tau Decays to Three Leptons written by and published by . This book was released on 2008 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using approximately 350 million [tau]+[tau]- pair events recorded with the BaBar detector at the Stanford Linear Accelerator Center between 1999 and 2006, a search has been made for neutrinoless, lepton-flavor violating tau decays to three lighter leptons. All six decay modes consistent with conservation of electric charge and energy have been considered. With signal selection efficiencies of 5-12%, we obtain 90% confidence level upper limits on the branching fraction [beta]}([tau] → lll) in the range (4-8) x 10-8.

Book excerpt: A search for the neutrinoless double beta decay of 1°°Mo was conducted using thin Mo films and solid state Si detectors. The experiment has collected 3500 hours of data operating underground in a deep silver mine (3290 M.W.E.). Only one event was found to be consistent with neutrinoless double beta decay. Using this one event, a limit of greater than or equal to 1 x 1022 years (1 sigma) is set on the 1°°Mo half-life. This is approximately five times larger than the best previous 1°°Mo limit.
