The study focuses on probing the strength of H(+/-)W(-/+)Z interaction in new physics models at a 27 TeV proton-proton collider, finding that the H-+/- jj production process has a greater reach compared to ZH(+/-), and the discovery potential of a charged Higgs improves markedly with respect to lower centre-of-mass energies. The results are also discussed in the context of the popular Georgi-Machacek model.
An H(+/-)W(-/+)Z interaction at the tree level is a common feature of new physics models that feature scalar triplets. In this study, we aim to probe the strength of the aforementioned interaction in a model-agnostic fashion at the futuristic 27 TeV proton-proton collider. We assume that the H-+/- couples dominantly to (W-+/-, Z) and (t, b) and specifically study the processes that involve the H(+/-)W(-/+)Z vertex at the production level, that is, pp -> H-+/- jj and pp -> ZH(+/-). Moreover, we look into both H-+/- -> W(+/-)Z, tb decays for either production process. Our investigations reveal that the H-+/- jj production process has a greater reach compared to ZH(+/-). Moreover, the discovery potential of a charged Higgs improves markedly with respect to the earlier studies corresponding to lower centre-of-mass energies. Finally, we recast our results in the context of the popular Georgi-Machacek model.
