The post-Higgs MSSM scenario: habemus MSSM?
We analyze the Minimal Supersymmetric extension of the Standard Model that we have after the discovery of the Higgs boson at the LHC, the hMSSM (habemus MSSM?), i.e. a model in which the lighter h boson has a mass of approximately 125 GeV which, together with the non-observation of superparticles at the LHC, indicates that the SUSY-breaking scale MS is rather high, MS ≳1 TeV. We first demonstra...
متن کاملMssm Higgs Searches at Lep2
Since it explains how the weak gauge bosons acquire their mass, the Higgs mechanism is a key point of the electroweak theory. In the Standard Model (SM), the Higgs mechanism predicts the existence of a scalar massive particle, the Higgs boson, which has never been observed yet. Because the SM is hardly consistent with the hierarchy between the Planck scale and the electroweak scale, it is certa...
متن کاملSneutrino Cold Dark Matter in Extended Mssm Models
A thorough analysis of sneutrinos as dark matter candidates is performed, in different classes of supersymmetric models, as is typically done for the neutralino dark matter. First in the Minimal Supersymmetric Standard Model, sneutrinos are marginally compatible with existing experimental bounds, including direct detection, provided they compose a subdominant component of dark matter. Then supe...
متن کاملPhenomenology of Light MSSM Higgs Boson Scenario
We have found that in the MSSM, the possibility for the lightest CP-even Higgs boson to be lighter than Z boson (as low as about 60 GeV) is, contrary to the usual belief, not yet excluded by LEP2 Higgs search nor any direct searches for supersymmetric particles at high energy colliders. The Light Higgs boson scenario (LHS) is realised when the ZZh coupling and the decay branching ratio Br(h/A →...
متن کاملMeasuring Trilinear Higgs Couplings in the MSSM
Trilinear couplings of the neutral CP -even Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) can be measured through the multiple production of the lightest CP -even Higgs boson (h) at high-energy ee colliders. This includes the production of the heavier CP -even Higgs boson (H) via ee → ZH, in association with the CP -odd Higgs boson (A) in ee → AH, or via ee → νeν̄eH, with H su...
