Higgs Boson Decays in the Minimal Supersymmetric Standard Model with Radiative Higgs Sector CP Violation
We re–evaluate the decays of the Higgs bosons in the minimal supersymmetric standard model (MSSM) where the tree-level CP invariance of the Higgs potential is explicitly broken by the loop effects of the third–generation squarks with CP–violating soft–breaking Yukawa interactions. This study is based on the mass matrix of the neutral Higgs bosons that is valid for arbitrary values of all the re...
متن کاملHiggs boson decays in the Complex MSSM
The analysis of the Higgs search results at LEP showed that a part of the MSSM parameter space with non-zero complex phases could not be excluded, where the lightest neutral Higgs boson, h1, has a mass of only about 45 GeV and the second lightest neutral Higgs boson, h2, has a sizable branching fraction into a pair of h1 states. Full one-loop results for the Higgs cascade decay h2 → h1h1 are pr...
متن کاملHiggs Boson Decays into Charginos and Neutralinos including Full One-loop Corrections
We present the one-loop corrected decay widths of a neutral (charged) Higgs boson into a chargino or neutralino pair (chargino and neutralino) in the CP-conserving MSSM. The chargino and neutralino parameters are renormalized in the on-shell scheme and it is shown that the correction due to the chargino/neutralino mass matrix renormalization is comparable to the conventional vertex correction. ...
متن کاملLEP Limits on CP - Violating Non - Minimal Higgs Sectors
We derive a sum rule which shows how to extend LEP limits on the masses of the lightest CP-even and CP-odd Higgs bosons of a CP-conserving two-Higgs-doublet model to any two Higgs bosons of a general CP-violating two-Higgs-doublet model. We generalize the analysis to a Higgs sector consisting of an arbitrary number of Higgs doublets and singlets, giving explicit limits for the CP-conserving and...
متن کاملHigher-order Corrections to Higgs-boson Decays *
One of the great puzzles of elementary particle physics today is whether nature makes use of the Higgs mechanism of spontaneous symmetry breaking to generate the observed particle masses. The Higgs boson, H , is the missing link sought to verify this concept in the Standard Model. Many of the properties of the Higgs boson are fixed, e.g., its couplings to the gauge bosons, gV VH = 2 G 1/2 F M 2...
