Light charged Higgs boson production at future $ep$ colliders

Abstract

We present a recent study of light charged Higgs boson ($H^{-}$) production at the Large Hadron electron Collider (LHeC). We study the charged current production process $e^{-}p\to {\nu }_{e}q{H}^{-}$, taking in account the decay channels $H^{-}\to b\bar{c}$ and $H^{-}\to \tau {\bar{\nu }}_{\tau }$. We analyse the process in the framework of the 2-Higgs Doublet Model Type-III (2HDM-III), assuming a four-zero texture in the Yukawa matrices and a general Higgs potential. We consider a variety of both reducible and irreducible backgrounds for the signals of the $H^{-}$ state. We show that the detection of a light charged Higgs boson is feasible, assuming for the LHeC standard energy and luminosity conditions.
