“…[89][90][91][92][93][94][95]. 3 While the assumptions that lead to these generic power counting estimates hold for many models of new physics, there are also exceptions: if there are, for example, different sources of electroweak symmetry breaking for different generations of fermions, it could be that the Higgs couplings to the light fermions are enhanced by larger factors, see [96].…”

We perform a Bayesian statistical analysis of the constraints on the nonlinear Effective Theory given by the Higgs electroweak chiral Lagrangian. We obtain bounds on the effective coefficients entering in Higgs observables at the leading order, using all available Higgs-boson signal strengths from the LHC runs 1 and 2. Using a prior dependence study of the solutions, we discuss the results within the context of natural-sized Wilson coefficients. We further study the expected sensitivities to the different Wilson coefficients at various possible future colliders. Finally, we interpret our results in terms of some minimal composite Higgs models.

“…Recently, the LHC Run I data confirm the SM Higgs-like nature of the 125 GeV boson discovered at the LHC [3][4][5][6]. If the light CP-even Higgs h in the 2HDM is identified with the observed 125 GeV boson, global fits to the LHC Higgs data suggest that all four types of 2HDM should lie close to the so-called alignment limit [78][79][80][81][82][83][84] …”

We revisit the rare leptonic decay B s → μ + μ − in the two-Higgs doublet models (2HDMs) with a softly broken Z 2 symmetry, namely type-I, type-II, type-X and type-Y 2HDMs. We have derived the relevant full one-loop Wilson coefficients of the four 2HDMs from the recent calculation in the aligned 2HDM by Li, Lu and Pich, which could be mapped to all the four 2HDMs for both large and small tan β. It is found that a new term associated with the soft Z 2 symmetry breaking parameter M can be enhanced by tan 2 β in the type-II 2HDM, which has not been considered in the literature. Imposing both theoretical and experimental constraints, we have renewed the bounds on the parameter spaces of the four 2HDMs. Different from our previous paper, however, we find that all the four 2HDMs give sizable and similar contributions to B(B s → μ + μ − ) within the stringently restricted parameter spaces, but very tiny as regards the mass-eigenstate rate asymmetry A ; this makes it unfeasible to discriminate the four types of 2HDM with the correlations between the observables in B s → μ + μ − decay.

“…The signal strengths moreover depend on the Higgs production cross sections in the X channel (σ SM X and σ X ) and branching ratios associated with the h → Y decay mode (BR(h → Y ) and BR SM (h → Y )) both in the Standard Model and in the NMSSM. Making use of the NMSSM signal strengths predicted by NmssmTools and the experimental measurements at the LHC [10,11], we construct a χ 2 quantity [43] Lilith-1.1.3 program using the 15.09 database [44], and we require χ 2 Y < 6.18 so that our NMSSM predictions are compatible at the 2σ level with data.…”

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.
