Book excerpt: OAK B188 The physics of kaon decays: CP violation and lepton flavor nonconservation. We discuss here the research that is likely to be done in the 1990's in the study of kaon decays. We concentrate on searches for direct CP violation and for the violation of electron- and muon-number, including approved and proposed experiments at existing facilities, and those which could be done at a facility using the proposed Fermilab Main Injector.

Available in PDF, EPUB and Kindle. Book excerpt: A search for the lepton-flavor-violating decay of the tau into one charged lepton and two charged hadrons has been performed using 221.4 fb−1 of data collected at an ee− center-of-mass energy around 10.58 GeV with the BABAR detector at the PEP-II storage ring. In all 14 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 (0.7-4.8) x 10−7 at 90% confidence level. All results are preliminary.

Download or read book Search for Lepton Flavor Violating Decay ?- {u2192}l-l+l-l written by and published by . This book was released on 2010 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model (SM) is one of the most tested and verified physical theories of all time, present experimental observations are consistent with SM expectations. On the other hand SM can not explain many physical observations: the cosmological observations possibly infer the presence of dark matter which is clearly beyond the SM expectations; the SM Higgs model, while explaining the generation of fermion masses, can not explain the hierarchy problem and a non natural fine tuning of SM is needed to cancel out quadratic divergences in the Higgs boson mass. New physics (NP) beyond SM should hence be investigated: rising the energy above NP processes thresholds, and detecting new particles or new effects not predicted by the standard model directly, is one of the possible approaches; another approach is to make precision measurements of well known processes or looking for rare processes which involve higher order contribution from NP processes, this approach need higher luminosities with respect to the previous approach but lower beam energies. Search for Lepton Flavor Violation (LFV) in charged lepton decays is promising: neutrino physics provides indeed a clear and unambiguous evidence of LFV in the neutral lepton sector via mixing processes, which have been observed for the first time by the Homestake collaboration. We expect LFV in the charged sector as well, both in ? and ? sector, but current experimental searches for LFV processes did not find any evidence for those processes, and more results are expected to come from new experiments in the coming years.

Download or read book A Search for Lepton Flavor Violation in Tau Decays at BABAR. written by O. Igonkina and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a recent BABAR search for lepton flavor violation in tau decays. The search for {tau} {yields} {ell}{ell}{ell} ({ell} = e, {mu}) decays is based on a data sample of 91.6 fb{sup -1}. No signal is found in any of six channels and 90% CL upper limits are set in the range of (1-3) x 10{sup -7}. The search for {tau} {yields} {mu}{gamma} decay is done with a 63 fb{sup -1} data sample. The number of observed events is consistent with expected background level and a preliminary upper limit is set at 2 x 10{sup -6} at 90% CL.
