Multilepton signatures of the Higgs boson through its production in association with a top-quark pair
Abstract
We consider the possible production of the Higgs boson in association with a top-quark pair and its subsequent decay into a tau-lepton pair or a W-boson pair. This process can give rise to many signatures of the Higgs boson. These signatures can have electrons, muons, tau jets, bottom jets and/or light flavor jets. We analyze the viability of some of these signatures. We will look at those signatures where the background is minimal. In particular, we explore the viability of the signatures “isolated 4 electron/muon” and “isolated 3electron/muon+ajet.” The jet can be due to a light flavor quark/gluon, a bottom quark, or a tau lepton. Of all these signatures, we find that “isolated 3electron/muon+ataujet,” with an extra bottom jet, can be an excellent signature of this mode of the Higgs boson production. We show that this signature may be visible within a year, once the Large Hadron Collider (LHC) restarts. Some of the other signatures would also be observable after the Large Hadron Collider accumulates sufficient luminosity.
