“…Consequently, it is of interest to test how well the more rigid structure of SUSY Higgs sectors containting two doublets and (at least) one singlet can describe the excesses. It was shown that indeed such models can accomodat the LEP and the CMS excesses at the 1 − 1.5 σ level, while being in agreement with all experimental data [13][14][15][16][17][18] (for reviews see Refs. [7,19,20]).…”

The CMS collaboration reported a ∼ 3 σ (local) excess at 96 GeV in the search for light Higgs-boson decaying into two photons. This mass coincides with a ∼ 2 σ (local) excess in the b b final state at LEP. We show an interpretation of these possible signals as the lightest Higgs boson in the 2 Higgs Doublet Model with an additional complex Higgs singlet (2HDMS). The interpretation is in agreement with all experimental and theoretical constraints. We concentrate on the 2HDMS type II, which resembles the Higgs and Yukawa structure of the Next-to Minimal Supersymmetric Standard Model. We discuss the experimental prospects for constraining our explanation at future e + e − colliders, with concrete analyses based on the ILC prospects.

“…Also in Ref. [59] the two-body Higgs decays into SM final states were considered at the full one-loop order. Similar projects have been presented for the THDM and its extensions [60][61][62].…”

“…It was observed in Ref. [59] that the decays of heavy new-physics Higgs states into SM particles could receive sizable radiative corrections beyond the well-known QCD effects [64,65]. It is desirable to control such corrections for a better characterization of the expected signals at colliders and a more quantitative implementation of associated limits.…”

“…In any case, from order-counting it appears mandatory to take the three-body final states into account if one wants to perform a consistent analysis of the branching ratios for two-body decays of heavy Higgs bosons at the full one-loop order. To our knowledge, such effects have not been considered in the NMSSM (or the MSSM) yet, and we expose here how we implement these channels in view of a future inclusion within a version of FeynHiggs [67][68][69][70][71][72][73][74] dedicated to the NMSSM [59,75,76].…”

Extensions of the Standard Model often come with additional, possibly electroweakly charged Higgs states, the prototypal example being the Two-Higgs-Doublet Model. While collider phenomenology does not exclude the possibility for some of these new scalar fields to be light, it is relatively natural to consider masses in the multi-TeV range, in which case the only remaining light Higgs boson automatically receives SM-like properties. The appearance of a hierarchy between the new-physics states and the electroweak scale then leads to sizable electroweak corrections, e. g. in the decays of the heavy Higgs bosons, which are dominated by effects of infrared type, namely Sudakov logarithms. Such radiative contributions obviously affect the two-body decays, but should also be paired with the radiation of electroweak gauge bosons (or lighter Higgs bosons) for a consistent picture at the one-loop order. Resummation of the leading terms is also relatively easy to achieve. We re-visit these questions in the specific case of the fermionic decays of heavy Higgs particles in the Next-to-Minimal Supersymmetric Standard Model, in particular pointing out the consequences of the three-body final states for the branching ratios of the heavy scalars. *

“…[25]) can be evaluated using the full SM one-loop result [26] combined with the appropriate effective couplings [27] (see, however, Ref. [28]). The full one-loop corrections in the cMSSM listed here together with resummed SUSY corrections have been implemented into the code FeynHiggs [27,[29][30][31][32][33].…”
