Higgs – Mediated B 0 → μ + μ − in Minimal Supersymmetry
In this letter we demonstrate a new source for large flavor–changing neutral currents within the minimal supersymmetric standard model. At moderate to large tan β, it is no longer possible to diagonalize the masses of the quarks in the same basis as their Yukawa couplings. This generates large flavor–violating couplings of the form bRdLφ and bRsLφ where φ is any of the three neutral, physical H...
متن کاملHiggs Limit and b → sγ Constraints in Minimal Supersymmetry
New limits on the Higgs mass from LEP and new calculations on the radiative (penguin) decay of the b-quark into sγ restrict the parameter space of the Constrained Minimal Supersymmetric Standard Model (CMSSM). We find that for the low tan β scenario only one sign of the Higgs mixing parameter is allowed, while the high tan β scenario is practically excluded, if one requires all sparticles to be...
متن کاملDiscovering the Higgs bosons of minimal supersymmetry with muons.
The prospects of detecting neutral Higgs bosons in the minimal supersymmetric model via their decays into muon pairs at the LHC are investigated. The CMS detector performance is adopted for a realistic study of observability. It is found that the muon pair decay mode might provide a very promising channel to search for the neutral Higgs bosons of minimal supersymmetry. This channel will allow p...

متن کاملFinite Higgs mass without supersymmetry
We identify a class of chiral models where the one-loop effective potential for Higgs scalar fields is finite without any requirement of supersymmetry. It corresponds to the case where the Higgs fields are identified with the components of a gauge field along compactified extra dimensions. We present a six dimensional model with gauge group U(3)×U(3) and quarks and leptons accomodated in fundam...
