Beyond the standard Higgs after the 125 GeV Higgs discovery.
An elementary weakly coupled and solitary Higgs boson allows one to extend the validity of the Standard Model up to very high energy, maybe as high as the Planck scale. Nonetheless, this scenario fails to fill the universe with dark matter and does not explain the matter-antimatter asymmetry. However, amending the Standard Model tends to destabilize the weak scale by large quantum corrections t...
متن کاملNaturalness of EWSB in NMSSM and Higgs at 100 GeV
Naturalness of electroweak symmetry breaking in the next-to-minimal supersymmetric model points to scenarios in which the lightest CP-even Higgs boson has SM-like ZZh coupling and mass mh ∼ 100 GeV and decays partly via h → bb̄ but dominantly into two CP-odd Higgs bosons, h → aa, where ma < 2mb so that a → τ+τ− (or light quarks and gluons) decays are dominant. These preferred scenarios correlate...
متن کاملSupersymmetric exotic decays of the 125 GeV Higgs boson.
We reveal a set of novel decay topologies for the 125 GeV Higgs boson in supersymmetry which are initiated by its decay into a pair of neutralinos, and discuss their collider search strategies. This category of exotic Higgs decays is characterized by the collider signature: visible objects+E_{T}, with E_{T} dominantly arising from escaping dark matter particles. Their benchmark arises naturally...
متن کاملMass-degenerate Higgs bosons at 125 GeV in the two-Higgs-doublet model
The analysis of the Higgs boson data by the ATLAS and CMS Collaborations appears to exhibit an excess of h ! events above the Standard Model (SM) expectations, whereas no significant excess is observed in h ! ZZ ! four lepton events, albeit with large statistical uncertainty due to the small data sample. These results (assuming they persist with further data) could be explained by a pair of nea...
متن کاملHiggs Masses and Couplings in the Nmssm
We give the upper bounds on the masses of the lightest and second lightest CP even Higgs bosons in the NMSSM, the MSSM extended by a gauge singlet. The dominant two loop corrections are included. Since the coupling R of the lightest Higgs scalar to gauge bosons can be small, we study in detail the relation between masses and couplings of both lightest scalars. We present upper bounds on the mas...
