Various aspects of the Higgs boson phenomenology of the Minimal Supersymmetric Standard Model (MSSM) are reviewed. Emphasis is put on the effects of higher-order corrections. The masses and couplings are discussed in the MSSM with real and complex parameters. Higherorder corrections to Higgs boson production channels at a prospective e+e− linear collider are investigated. Corrections to Higgs b...

We review the phenomenology of light Higgs scalars in supersymmetric left-right models. We consider models with minimal particle content (with and without non-renormalizable higher-dimensional terms) and with additional Higgs superfields. The upper bound on the lightest CP -even neutral Higgs boson in these models is larger than in the minimal supersymmetric standard model, and the Higgs coupli...

I summarize our results on the attainable limits on the coefficients of dimension–6 operators from the analysis of Higgs boson phenomenology using data taken at Tevatron RUNI and LEPII. Our results show that the coefficients of Higgs–vector boson couplings can be determined with unprecedented accuracy. Assuming that the coefficients of all “blind” operators are of the same magnitude, we are als...

Supersymmetry. According to the theory of unbroken supersymmetry, for each fermion there exists a boson superpartner and for each boson there exists a fermion superpartner with the same fundamental characteristics (including mass and charge). But, broken supersymmetry states that all superpartners have masses much greater than their associated particles, leaving no hope to observe the unbroken ...

We suggest that the Standard Model may undergo a supercritical transition near the Landau scale, where the U(1) gauge boson couples to the left and right handed states of any given fermion with different charges. This scenario naturally gives rise to three generations of fermion, corresponding to the three critical scales for the right-right, right-left and left-left fermion interactions going ...

We evaluate O(αbαs) corrections in the MSSM Higgs boson sector, including an analysis of the renormalization in the bottom/scalar bottom sector. For μ < 0 the genuine two-loop corrections to the mass of the lightest Higgs boson mass can amount up to 3 GeV. Different renormalization schemes are applied and numerically compared. Likewise the residual dependence on the renormalization scale is inv...

We review the realization of the Brout-Englert-Higgs mechanism in the electroweak theory and describe the experimental and theoretical constraints on the mass of the single Higgs boson expected in the minimal Standard Model. We also discuss the couplings of this Higgs boson and its possible decay modes as functions of its unknown mass. We then review the structure of the Higgs sector in the min...

We discuss the ground state and the small-amplitude excitations of dilute bosonfermion mixtures confined in spherical harmonic traps at T = 0, assuming repulsive boson-boson interactions and with each component being in a single hyperfine state. From previous studies of the equilibrium density profiles we propose a schematic phase diagram in a plane defined by the variables abf/abb and abbk (0)...
