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 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 کاملDirac Gauginos and Kinetic Mixing
We present formulae for the calculation of Dirac gaugino masses at leading order in the supersymmetry breaking scale using the methods of analytic continuation in superspace and demonstrate a link with kinetic mixing, even for non-abelian gauginos. We illustrate the result through examples in field and string theory. We discuss the possibility that the singlet superfield that gives the U(1) gau...
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 کاملct 2 01 5 125 GeV Higgs boson mass from 5 D gauge - Higgs unification
In the context of a simple gauge-Higgs unification (GHU) scenario based on the gauge group SU(3)×U(1)′ in a 5-dimensional flat space-time, we investigate a possibility to reproduce the observed Higgs boson mass of around 125 GeV. We introduce bulk fermion multiplets with a bulk mass and a (half) periodic boundary condition. In our analysis, we adopt a low energy effective theoretical approach o...
