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).
