Higgs sector CP violation in the Minimal Supersymmetric Model
We study the possibility that CP is spontaneously broken in the Minimal Supersymmetric Model when radiative corrections to the Higgs potential are included. We show that this can only occur if a light Higgs boson exists. Considering the recent ALEPH Higgs search, we exclude most of the parameter space of the model. The possibility of explicit CP violation in the model is also briefly discussed....
متن کاملRenormalization-group-improved Higgs sector of the minimal supersymmetric model.
In the minimal supersymmetric model (MSSM) all Higgs self-coupling parameters are related to gauge couplings at tree-level. Leading-logarithmic radiative corrections to these quantities can be summed using renormalization group techniques. By this procedure we obtain complete leading-log radiative corrections to the Higgs masses, the CP-even Higgs mixing angle, and trilinear Higgs couplings. Ad...
متن کاملHiggs Boson Masses and Couplings in the Minimal Supersymmetric Model
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...
متن کاملHiggs Scalar-Pseudoscalar Mixing in the Minimal Supersymmetric Standard Model
In the minimal supersymmetric Standard Model, the heaviest CP-even Higgs boson H and the CP-odd Higgs scalar A are predicted to be almost degenerate in mass at the tree level, for the wide kinematic range MA > 2MZ and tanβ ≥ 2. However, if large soft-CPviolating Yukawa interactions involving scalar quarks of the third generation are present in the theory, then the CP invariance of the Higgs pot...
متن کاملHiggs Sector in Extensions of the Minimal Supersymmetric Standard Model
Extensions of the minimal supersymmetric standard model (MSSM) with additional singlet scalar fields solve the important μ-parameter fine-tuning problem of the MSSM.We compute and compare the neutral Higgs boson mass spectra, including one-loop corrections, of the following MSSM extensions: next-tominimal supersymmetric standard model (NMSSM), the nearly-minimal supersymmetric standard model (n...
