Bounds on the Higgs Mass in the Standard Model and the Minimal Supersymmetric Standard Model A
Depending on the Higgs-boson and top-quark masses, M H and Mt, the effective potential of the Standard Model can develop a non-standard minimum for values of the field much larger than the weak scale. In those cases the standard minimum becomes metastable and the possibility of decay to the non-standard one arises. Comparison of the decay rate to the non-standard minimum at finite (and zero) te...
متن کاملBounds on the Higgs Mass in the Standard Model and Minimal Supersymmetric Standard Model
We present bounds on the Higgs mass in the Standard Model and in the Minimal Supersymmetric Standard Model using the effective potential with nextto-leading logarithms resummed by the renormalization group equations, and physical (pole) masses for the top quark and Higgs boson. In the Standard Model we obtain lower bounds from stability requirements: they depend on the top mass and the cutoff s...
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...
متن کاملUnification Constraints in the Next - to - Minimal Supersymmetric Standard Model
We perform a renormalisation group analysis of the next-to-minimal su-persymmetric standard model (NMSSM) based on the following constraints: two-loop gauge coupling unification at a variable scale M X , running the gauge couplings through the low energy thresholds; universal soft supersym-metry breaking parameters; correct electroweak symmetry breaking. The phenomenological implications of our...
