Download or read book Limits on Tau Lepton Flavor Violating Decays in Three Charged Leptons written by and published by . This book was released on 2010 with total page pages. 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.

Book excerpt: The Standard Model of particle physics is a highly successful theory of fundamental particle interactions, especially in light of the recent discovery of a Higgs-like boson at the LHC. Nonetheless, the SM is incomplete, and the search for physics beyond the SM has prompted a great amount of experimental and theoretical work. In this thesis, I present theoretical work I have done in two areas of beyond the SM physics: scalar dark matter and lepton flavor violation. Scalar extensions of the SM are simple but nonetheless interesting and well-motivated models for beyond the SM physics that can include a dark matter candidate particle. Using the renormalization group evolution of the model parameters and the Coleman-Weinberg one-loop effective potential, I perform an analysis of the vacuum stability of two of these scalar extensions, the real singlet and the complex singlet. Also included are experimental bounds from dark matter direct detection. The vacuum stability analysis reveals that light dark matter (10 GeV) requires a moderate self-interaction strength and new physics at or below the 109 GeV scale in the case of the real scalar, and a light (order 10 to 100 GeV) Higgs-like particle with reduced couplings and additional new physics below 1000 TeV in the case of the complex scalar. Lepton flavor violation probes the high energy scale of new physics through its effects on low energy processes which are highly suppressed in the SM by small neutrino masses. I utilize the Buchmuller-Ruckl-Wyler parameterization of leptoquarks and limits obtained from the HERA experiments ZEUS and H1 to calculate the cross section for electron-to-tau conversion in DIS at a next generation Electron-Ion Collider (EIC) with high luminosity. The potential for the EIC to search for such events is compared with the ability of future tau-to-e-gamma searches to set limits on leptoquark masses and couplings. This analysis demonstrates that a future EIC search would be competitive with or surpass limits from tau decays, especially in the case of one particular leptoquark which evades the tau-to-e-gamma bound.

Download or read book Search for the Lepton Flavor Violating Decay Z Implies Epsilon Mu with the ATLAS Detector written by D. T. Pignotti and published by . This book was released on 2014 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ATLAS detector at the Large Hadron Collider is used to search for the lepton flavor violating process Z -> eμ in pp collisions using 20.3 fb^(-1) of data collected at sqrt(s)= 8 TeV. An enhancement in the eμ invariant mass spectrum is searched for at the Z boson mass. The number of Z bosons produced in the data sample is estimated using events of similar topology, Z -> ee and μμ, significantly reducing the systematic uncertainty in the measurement. There is no evidence of an enhancement at the Z boson mass, resulting in an upper limit on the branching fraction, B(Z -> eμ)

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.
