“…[46] show that after all cuts, the left cross section of the signal is 1 fb when m H AE ¼ 500 GeV, and the backgrounds are becoming negligibly small. Reference [46] also points out in Tables I and II, that with the increasing charged scalar mass, the backgrounds become smaller and easier to be suppressed, so it seems that the larger the charged scalar mass is, the easier it is to detect the W production at the LHC, though the cross section of the signals will also be smaller.…”

Many new physics models beyond the standard model, such as the littlest Higgs models and the leftright twin Higgs models, predict the existence of the large charged Higgs couplings H À q " b and H þ b " q, where q ¼ t or the new vectorlike heavy quark T. On the other hand, some new physics models, like the littlest Higgs, also predict the gauge-Higgs couplings. Such couplings may have rich collider phenomenology. We focus our attention on these couplings induced by the littlest Higgs models and the left-right twin Higgs models and consider their contributions to the production cross section for W AE H Ç production at the large hadron colliders. We find that the cross sections in the littlest Higgs models on the parton level gg ! W AE H Ç and q " q ! W AE H Ç (q ¼ u, d, s, c, b) may reach tens of dozens femtobarns in reasonable parameter space at the collision energy of 14 TeV and that the total cross section can even reach a few hundred femtobarns in certain favored space. While in the left-right twin Higgs models, the production rates are basically one order lower than those in the littlest Higgs models. Therefore, due to the large cross sections of that in the littlest Higgs models, it may be possible to probe the charged Higgs via this process in a certain parameter space.

Models of electroweak symmetry breaking with extended Higgs sectors are theoretically well motivated. In this study, we focus on models with a low energy spectrum containing a pair of charged scalars H ± , as well as a light scalar H and/or a pseudoscalar A. We study the H ± tb associated production with H ± → AW ± /HW ± , which could reach sizable branching fractions in certain parameter regions. With detailed collider analysis, we obtain the exclusion bounds as well as discovery reach at the 14 TeV LHC for the process pp → H ± tb → AW ± tb/HW ± tb → τ τ bbW W, bbbbW W . We find that for a daughter particle mass of 70 GeV, the 95% C.L. exclusion reach in σ × BR varies from about 60 fb to 25 fb, for m H ± ranging from 150 GeV to 500 GeV with 300 fb −1 integrated luminosity in the τ τ mode. We further interpret these bounds in the context of Type II Two Higgs Doublet Model. The exclusion region in the m H ± −tan β plane can be extended to m H ± = 600 GeV, while discovery is possible for m H ± 400 GeV with 300 fb −1 integrated luminosity. The exotic decay mode H ± → AW ± /HW ± offers a complementary channel to the conventional mode H ± → τ ν for charged Higgs searches.

The presence of charged Higgs bosons is a generic prediction of multiplet extensions of the Standard Model (SM) Higgs sector. Focusing on the Two-Higgs-Doublet-Model (2HDM) with type I and lepton-specific Yukawa sectors, we discuss the charged Higgs boson collider phenomenology in the theoretically and experimentally viable parameter space. While almost all existing experimental searches at the LHC target the fermionic decays of charged Higgs bosons, we point out that the bosonic decay channels — especially the decay into a non-SM-like Higgs boson and a W boson — often dominate over the fermionic channels. Moreover, we revisit two genuine BSM effects on the properties of the discovered Higgs boson — the charged Higgs contribution to the diphoton rate and the Higgs decay to two light Higgs bosons — and their implication for the charged Higgs boson phenomenology. As main result of the present paper, we propose five two-dimensional benchmark scenarios with distinct phenomenological features in order to facilitate the design of dedicated LHC searches for charged Higgs bosons decaying into a W boson and a light, non-SM-like Higgs boson.
