Left And Right

The results of the QCD corrections to the [Formula: see text] decay within the minimal super-symmetric standard model such that gluinos and scalar quarks are taken within the relevant loop diagram are presented. The mixing of the scalar partners of the left- and right-handed top quarks which is proportional to the top quark mass is included. The standard corrections via gluons and quarks are about +7% for a charged Higgs mass of 300 GeV and about −10% for a Higgs mass of 800 GeV. The standard corrections can be shown to diminish or enhance by a non-negligible amount of certain values of the supersymmetric parameter space. The sign changes can also be obtained.

Neutral Scalar

We discuss the supersymmetric standard model from the perspective that the up and down Higgs supermultiplets are composite states. We show that a Higgs multiplet in which the scalar states are bound states of two squarks and the corresponding Higgsinos are bound states of a quark and a squark has the correct supersymmetry transformations and may lead to an alternative model which contains additional effective operators and which displays dynamical symmetry breaking. We describe this model through an effective Higgs potential which by itself may lead to the correct mass of 125.9 GeV for the lightest Higgs boson and to other neutral scalar masses respecting the experimental constraints.

Focus Point

We investigate the focus points of the renormalization group equations of the minimal supersymmetric standard model. We show that within this model the up- and down-type Higgs mass soft supersymmetry breaking parameters have focus point behavior at the electroweak scale simultaneously when appropriate conditions are fulfilled. The focus point scenario holds for large tan β. This two-focus-point scenario allows to fix the pole top-quark mass which is within the experimentally allowed interval. The main goal of this paper is the investigation of the influence of the existence of focus points on the determination of the mass of the lightest Higgs boson.
