Single charged Higgs boson production at the LHC

A search for charged Higgs may yield clear and direct signs of new physics outside the realm of the Standard Model (SM). In the Two-Higgs Doublet Model (2HDM), we investigate two of the main single charged Higgs production channels at the Large Hadron Collider (LHC), assuming that either h or H replicates the detected resonance at similar to 125 GeV. We consider the possibility of the charged Higgs boson production through the pp -> H +/- W -/+ and pp -> H +/- bj production processes that may present additional significance at the LHC experiments. Considering the H +/- -> W +/- hi/A decay channels and mainly concentrating on the bb over line , Tau Tau and gamma gamma decays of hi and A, we examine the possible signatures arising from the aforementioned charged Higgs production and decay in both type-I and type-X realizations of 2HDM. Our study shows that these signatures can have sizable rates at low tan beta as long as the condition MH +/- < mt - mb is satisfied. As a result, we propose the bb, Tau Tau and gamma gamma final states associated with WW or Wbj as an encouraging experimental avenue that would complement the LHC search for a charged Higgs boson.(c) 2023 The Author(s).

Automated summary

A search for charged Higgs at LHC could provide clear evidence of new physics beyond the Standard Model. In this study, we investigate the production channels of charged Higgs through pp -> H +/- W -/+ and pp -> H +/- bj in the Two-Higgs Doublet Model. By examining the decay channels of H +/- -> W +/- hi/A, specifically focusing on bb over line, Tau Tau and gamma gamma decays of hi and A, we find that these signatures can have significant rates at low tan beta under certain conditions. We propose the bb, Tau Tau, and gamma gamma final states associated with WW or Wbj as a promising experimental approach to complement the search for a charged Higgs boson at LHC.
