Higgs boson phenomenology in tau^+ tau^- final states at the LHC

Abstract

We perform a detailed parton level study on the feasibility of the detection of a Higgs boson in the gluon fusion process $pp(gg+gq)\to h+jet\to {\tau }^{+}{\tau }^{-}+jet$ at the Large Hadron Collider (LHC). The obtained results are applied to a few chosen Beyond the Standard Model (BSM) scenarios where the branching ratio of a Higgs boson decaying into a ${\tau }^{+}{\tau }^{-}$ pair is enhanced as compared to the Standard Model (SM) case. We present the parameter space of the BSM scenarios that can be observed at the LHC and conclude that some regions of the parameter space can be probed with just a few $f{b}^{-1}$ of integrated luminosity. Noticeably, our results are presented in a form which potentially allows their application to any generic model giving rise to a $pp(gg+gq)\to h+jet\to {\tau }^{+}{\tau }^{-}+jet$ signature.
