Radiative corrections to the Higgs boson decay rate Γ ( H → ZZ ) in the minimal supersymmetric model
نویسنده
چکیده
We consider radiative corrections to the decay rate Γ(H → ZZ) of the heavy CP-even Higgs boson of the minimal supersymmetric model to two Z bosons. We perform a one loop Feynman diagram calculation in the on-mass-shell renormalization scheme, and include the third generation of quarks and squarks. The tree level rate is suppressed by a mixing angle factor and decreases as 1/MH for large MH . The corrected rate overcomes this suppression and increases with MH for MH>∼500 GeV. The corrections can be very large and depend in detail on the top squark masses and A-term, as well as the supersymmetric Higgs mass parameter μ.

Generalized screening theorem for Higgs decay processes in the two - doublet model
The radiative corrections to the decay processes of the neutral (CP -even) Higgs boson (H) into a longitudinal gauge boson pair, i.e., H → ZLZL and H → W L W− L are analyzed in the two-Higgs doublet model by assuming that all of the Higgs boson masses are much greater than the W and Z bosons’. These calculations are motivated to see if one could see potentially large virtual effects to these de...
متن کاملΓ Rate and Higgs Boson Limits in the Constrained Minimal Supersymmetric Model
New NLO b → X s γ calculations have become available using resummed radiative corrections. Using these calculations we perform a global fit of the supergravity inspired constrained minimal supersymmetric model. We find that the resummed calculations show similar constraints as the LO calculations, namely that only with a relatively heavy supersymmetric mass spectrum of O(1 TeV) the b − τ Yukawa...
متن کاملThe 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 کاملHiggs Boson Interactions in Supersymmetric Theories with Large Tan
We show that radiative corrections to the Higgs potential in supersymmetric theories with large tan generically lead to large diierences in the light Higgs boson decay branching fractions compared to those of the standard model Higgs boson. In contrast, the light Higgs boson production rates are largely unaaected. We identify W h associated production followed by Higgs boson decays to photons o...

The Higgs sector of the Minimal Supersymmetric Model (MSSM) is a CPconserving two-Higgs doublet model that depends, at tree-level, on two Higgs sector parameters. In order to accurately determine the phenomenological implications of this model, one must include the effects of radiative corrections. The leading contributions to the one-loop radiative corrections are exhibited; large logarithms a...
