Signature of the maximally symmetric 2HDM via W±/Z -quadruplet productions at the LHC

Abstract

We consider the maximally symmetric two-Higgs doublet model (MS-2HDM) in which the so-called Standard Model (SM) alignment can be achieved naturally by the virtue of an SO(5) symmetry imposed on the 2HDM. We investigate the signature of the MS-2HDM via → HX → VV ∗ X processes at the LHC for different values of tan β. We perform our calculations with next-to-leading-order (NLO) QCD accuracy, using the herwig7 multipurpose event generator at √s = 13 TeV center-of-mass energy. We show that the production of single SM-like Higgs bosons via W±/Z pairs is completely aligned with the SM. Interestingly, the presence of the heavy Higgs states significantly enhances the cross section for the W± /Z- quadruplet production channels in the low -p⊥ regions. These vital analyses may aid the future discovery of this minimal and very predictive extension of the SM and can be generalized to other realizations of the 2HDM.
