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 ∼ 125 GeV. We consider the possibility of the charged Higgs boson production through the p p → H ± W ∓ and p p → H ± b j production processes that may present additional significance at the LHC experiments. Considering the H ± → W ± h i / A decay channels and mainly concentrating on the b b ¯ , ττ and γγ decays of h i 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 ⁡ β as long as the condition M H ± < m t − m b is satisfied. As a result, we propose the bb , ττ and γγ final states associated with WW or Wbj as an encouraging experimental avenue that would complement the LHC search for a charged Higgs boson.
