“…The resulting effects in the Higgs sector have been studied in detail in the xSM [9,10,14,23,24]. These effects are also generically found in other more complex models that predict a scalar singlet, such as the class of singlet extended supersymmetric models [25,26,27,28,29,30,31,32,33,34,35] and Randall-Sundrum models where the radion-Higgs mixing is essentially equivalent to singlet-Higgs mixing [36,37]. The field A does not mix with the SM Higgs field in the U(1) symmetric scenario (B1); it will in general do so for the U(1)-breaking scenarios (B2) unless the CP-violating interactions are absent.…”

We analyze a simple extension of the Standard Model (SM) obtained by adding a complex singlet to the scalar sector (cxSM). We show that the cxSM can contain one or two viable cold dark matter candidates and analyze the conditions on the parameters of the scalar potential that yield the observed relic density. When the cxSM potential contains a global U (1) symmetry that is both softly and spontaneously broken, it contains both a viable dark matter candidate and the ingredients necessary for a strong first order electroweak phase transition as needed for electroweak baryogenesis. We also study the implications of the model for discovery of a Higgs boson at the Large Hadron Collider.

“…(4.9) and (4.10) are never fulfilled. However, one could increase the value ofλ 3 by augmenting the MSSM with either a singlet scalar, as in the case of NMSSM [71][72][73][74][75][76][77][78][79][80][81], or a triplet scalar [34,35]. In these models, a gauge singlet, S, in the case of NMSSM, and a triplet scalar, Σ, in the case of triplet augmented MSSM, are added to the superpotential with the following cubic couplings, among others,…”

In models with an extended Higgs sector there exists an alignment limit, in which the lightest CP-even Higgs boson mimics the Standard Model Higgs. The alignment limit is commonly associated with the decoupling limit, where all non-standard scalars are significantly heavier than the Z boson. However, alignment can occur irrespective of the mass scale of the rest of the Higgs sector. In this work we discuss the general conditions that lead to "alignment without decoupling", therefore allowing for the existence of additional non-standard Higgs bosons at the weak scale. The values of tan β for which this happens are derived in terms of the effective Higgs quartic couplings in general twoHiggs-doublet models as well as in supersymmetric theories, including the MSSM and the NMSSM. Moreover, we study the information encoded in the variations of the SM Higgsfermion couplings to explore regions in the m A − tan β parameter space.

We study a class of realizations of the Next-to-Minimal Supersymmetric Standard Model that is motivated by dark matter and Higgs data, and in which the lightest pseudoscalar Higgs boson mass is smaller than twice the bottom quark mass and greater than twice the tau lepton mass. In such scenarios, the lightest pseudoscalar Higgs boson can be copiously produced at the LHC from the decay of heavier superpartners and will dominantly further decay into a pair of tau leptons that is generally boosted. We make use of a boosted object tagging technique designed to tag such a ditau jet, and estimate the sensitivity of the LHC to the considered supersymmetric scenarios with 20 to 50 fb −1 of proton-proton collisions at a center-of-mass energy of 13 TeV.
