“…However the dominant QCD background to this signal was not identified. A more careful treatment of the dominant QCD backgrounds was carried out in [382], which concluded that the signal would still be nearly backgroundfree, with excellent prospects for discovery in early 14 TeV LHC running (considering exotic branching fractions of tens of percent).…”

We perform an extensive survey of nonstandard Higgs decays that are consistent with the 125 GeV Higgs-like resonance. Our aim is to motivate a large set of new experimental analyses on the existing and forthcoming data from the Large Hadron Collider (LHC). The explicit search for exotic Higgs decays presents a largely untapped discovery opportunity for the LHC collaborations, as such decays may be easily missed by other searches. We emphasize that the Higgs is uniquely sensitive to the potential existence of new weakly coupled particles and provide a unified discussion of a large class of both simplified and complete models that give rise to characteristic patterns of exotic Higgs decays. We assess the status of exotic Higgs decays after LHC run I. In many cases we are able to set new nontrivial constraints by reinterpreting existing experimental analyses. We point out that improvements are possible with dedicated analyses and perform some preliminary collider studies. We prioritize the analyses according to their theoretical motivation and their experimental feasibility. This document is accompanied by a Web site that will be continuously updated with further information [http://exotichiggs.physics .sunysb.edu].

“…Besides, since tau decays are always accompanied by neutrinos, there is no sharp peak of a 0 1 invariant mass. For these reasons, as discussed in the literature, 4µ [39,44,45], 4γ [21,33] or 2γ + 2-jets [46] search channels with m a 0 1 < 2m τ turn out to be the ideal way to probe NMSSM Higgses with very light pseudoscalars.…”

In this article we propose a simultaneous collider search strategy for a pair of scalar bosons in the NMSSM through the decays of a very light pseudoscalar. The massive scalar has a mass around 126 GeV while the lighter one can have a mass in the vicinity of 98 GeV (thus explaining an apparent LEP excess) or be much lighter. The successive decay of this scalar pair into two light pseudoscalars, followed by leptonic pseudoscalar decays, produces clean multi-lepton final states with small or no missing energy. Furthermore, this analysis offers an alternate leptonic probe for the 126 GeV scalar that can be comparable with the ZZ * search channel. We emphasize that a dedicated experimental search for multi-lepton final states can be an useful probe for this scenario and, in general, for the NMSSM Higgs sector. We illustrate our analysis with two representative benchmark points and show how the LHC configuration with 8 TeV center-of-mass energy and 25 fb −1 of integrated luminosity can start testing this scenario, providing a good determination of the light pseudoscalar mass and a relatively good estimation of the lightest scalar mass. *

“…It is well known that gluon fusion and b-quark fusion are the two main production processes of a Higgs at the LHC in the context of SUSY. Gluon fusion dominates over b-quark fusion in our benchmark points, as can be shown using the relevant equations [44]:…”

Abstract:The µνSSM is a supersymmetric standard model that accounts for light neutrino masses and solves the µ problem of the MSSM by simply using right-handed neutrino superfields. Since this mechanism breaks R-parity, a peculiar structure for the mass matrices is generated. The neutral Higgses are mixed with the right-and left-handed sneutrinos producing 8×8 neutral scalar mass matrices. We analyse the Higgs sector of the µνSSM in detail, with special emphasis in possible signals at colliders. After studying in general the decays of the Higges, we focus on those processes that are genuine of the µνSSM, and could serve to distinguish it form other supersymmetric models. In particular, we present viable benchmark points for LHC searches. For example, we find decays of a MSSM-like Higgs into two lightest neutralinos, with the latter decaying inside the detector leading to displaced vertices, and producing final states with 4 and 8 b-jets plus missing energy. Final states with leptons and missing energy are also found.
