摘要: The possibility of searching for the Higgs boson in channels with multiple non- resonant leptons is evaluated light recent advances multi-lepton search techniques at LHC. total signal exceeds four lepton gold-plated mode, but spread over many same-sign di-lepton, tri-lepton, and nal states. While any individual channel alone not signicant, exclusive combination across shown to provide a sensitivity nearly comparable other discovery level searches boson. We estimate that 5 fb 1 data, existing non-optimized LHC could exclude 95% CL few times predicted Standard Model cross section mass range 120 150 GeV. Renements focused specically on are suggested would further increase sensitivity. illustrate discerning patterns production decay modes using correlations by comparing sensitivities Model, Fermi-phobic, b-phobic bosons.
