Title: Phenomenology of vectorlike lepton extensions of the SM or two Higgs doublet model
Date (JST): Wed, Jan 06, 2016, 13:30 - 14:30
Place: Seminar Room A
Abstract: I will discuss the possibility that the Standard Model is extended by extra heavy leptons (vectorlike leptons). Such vectorlike leptons can contribute to multilepton with missing energy signal through Drell-Yan production and the Higgs discovery signal of ZZ* or WW* through exotic (SM) Higgs cascade decay. Extending the Higgs sector to include extra doublet, a heavy BSM Higgs cascade decay contribute a variety of diboson-like signals (including the SM Higgs boson). I will also discuss the discoveries of these signals, partly by using their unique kinematic topologies.
