This book was released on 2007 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors search for pair production of doubly charged Higgs particles (H{sup ±±}) followed by decays into electron-tau (e[tau]) and muon-tau ([mu][tau]) pairs using a data set corresponding to an integrated luminosity of 350 pb−1 collected from {bar p}p collisions at √s = 1.96 TeV by the CDF II experiment. They search separately for cases where three or four final-state leptons are detected, and then combine the results into limits for each exclusive flavor decay mode of the H{sup ±±}. Assuming 100% branching ratios of the H{sup {+-}{+-}} to left-handed e[tau] ([mu][tau]) pairs, they set an H{sup {+-}{+-}} lower mass limit of 114 (112) GeV/c2 at the 95% confidence level (C.L.).

Book Synopsis A Search for Double-charged Higgs Bosons at the Tevatron by : Sasha Baraoiant
Download or read book A Search for Double-charged Higgs Bosons at the Tevatron written by Sasha Baraoiant and published by . This book was released on 2006 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: We search for the pair production of doubly charged Higgs particles followed by the lepton-flavor violating decay of each Higgs into electron-and-tau and muon-and-tau pairs using 350 pb{sup -1} of data collected by the CDF II experiment at the Fermilab Tevatron. Separate searches investigate cases where three or four final state leptons are detected, and the limits for each exclusive decay mode reflect the combined results of both searches. Assuming the H{sup {+-}{+-}}{sub L} decays exclusively into like sign electron-and-tau pairs, we set a lower limit on its mass of 114 GeV/c2 at the 95 % confidence level. In the case of exclusive muon-and-tau decays, we set a lower mass limit of 112 GeV/c2 also at the 95% confidence level.

Available in PDF, EPUB and Kindle. Book excerpt: Two searches for the production of Higgs bosons decaying into [tau] and [mu] leptons, using data collected with the DØ detector at the Fermilab Tevatron p$\bar{p}$ collider, are presented. A search for the pair production of doubly charged Higgs bosons in the process q$\bar{q}$ 2!H++H--, where H ±± decays to [tau][tau], [mu][mu] or [tau][mu] lepton pairs, with an integrated luminosity of up to L = 7:0 fb-1, is presented. No signi cant excess of data over the expected SM background is observed and the results are used to set 95% C.L. limits on the pair production cross section of doubly charged Higgs bosons in the range 90

Download or read book Search for Lepton-flavour-violating Decays of the Higgs Boson written by and published by . This book was released on 2015 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first direct search for lepton-flavour-violating decays of the recently discovered Higgs boson (H) is described. The search is performed in the H 2![mu][tau]e and H2!mu][tau]h channels, where [tau]e and [tau]h are tau leptons reconstructed in the electronic and hadronic decay channels, respectively. The data sample used in this search was collected in pp collisions at a centre-of-mass energy of [arrow]" = 8 TeV with the CMS experiment at the CERN LHC and corresponds to an integrated luminosity of 19.7 fb−1. The sensitivity of the search is an order of magnitude better than the existing indirect limits. A slight excess of signal events with a significance of 2.4 standard deviations is observed. The p-value of this excess at MH=125 GeV is 0.010. The best fit branching fraction is [Beta](H 2![mu][tau])=(0.84+0.39-0.37)%. A constraint on the branching fraction, [Beta](H 2![mu][tau])

This book was released on 2015 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A direct search for lepton-flavour-violating H → [mu][tau] decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H → [mu][tau] had channel, where [tau] had is a hadronically decaying [tau] -lepton. The search is based on the data sample of proton-proton collisions collected by the ATLAS experiment corresponding to an integrated luminosity of 20.3 fb-1 at a centre-of-mass energy of √s = 8 TeV. No statistically significant excess of data over the predicted background is observed. As a result, the observed (expected) 95% confidence-level upper limit on the branching fraction, Br( H → [mu][tau] ), is 1.85% (1.24%).

This book was released on 2016 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a search for lepton-flavor-violating (LFV) decays of the 125 GeV Higgs boson in final states of \mu\tau_{\mathrm{had}} and e\tau_{\mathrm{had}} in the full dataset collected by the ATLAS detector in 2012. The search is based on data samples of proton--proton collisions at \sqrt{s} = 8 TeV, corresponding to an integrated luminosity of 20.3 fb^{-1}. The topology of LFV events is exploited through an optimized selection of objects and events, with signal and control regions defined by event kinematics. A binned likelihood fit searching for the presence of LFV Higgs decays is performed using the reconstructed Higgs boson mass as the discriminating variable. No such decays are observed. The expected (observed) upper limits at 95% confidence on the branching ratios for the muon and electron final states are found to be Br(H \rightarrow \mu\tau) = 1.24% (1.85%) and Br(H \rightarrow e\tau) = 2.07% (1.81%).
