Minimal Supersymmetric Extension

The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) is one of the most favored supersymmetric models. After an introduction to the model, the Higgs sector and the neutralino sector are discussed in detail. Theoretical, experimental, and cosmological constraints are studied. Eventually, the Higgs potential is investigated in the approach of bilinear functions. Emphasis is placed on aspects which are different from the minimal supersymmetric extension.

Minimal Supersymmetric Extension

We review the effective Lagrangian of the Higgs penguin in the Standard Model and its minimal supersymmetric extension (MSSM). As a master application of the Higgs penguin, we discuss in some detail the B-meson decays into a lepton–antilepton pair. Furthermore, we explain how this can probe the Higgs sector of the MSSM provided that some of these decays are seen at Tevatron Run II and B-factories. Finally, we present a complete list of observables where the Higgs penguin could be strongly involved.

Minimal Supersymmetric Extension

A gluino can decay into a color-singlet neutral fermion [Formula: see text] by radiating off a gluon. We study this process in a minimal supersymmetric extension of the standard model. A significant branching fraction is possible depending on how much [Formula: see text] overlaps with the Higgs fermion which couples to the t quark and the mass of the t quark itself.

Supersymmetric Models

In this paper the control parameters of the Higgs potential are considered in the framework of supersymmetric models MSSM and Next-to-MSSM. The determination of these parameters is an important part related to the explanation of the CP violation evidence and electroweak phase transition evolution from the energy of the supersymmetry scale to the standard model energy scale. There is a discussion here on the problem of violation of CP invariance and its effect on the Higgs potential control parameters determination and the dark matter experimental constraints. Also the problem of determining the Potential ↔ Free Energy parameters from the points of temperature field theory and critical temperatures view is considered.

Minimal Supersymmetric Extension

Direct search for neutralino dark matter is analyzed in the framework of the minimal supersymmetric extension of the standard model, using a realistic evaluation of the neutralino relic abundance which also includes radiative corrections to the Higgs masses. Relevance of the present (Ge detectors) experimental data to set constraints on the parameters of the model is discussed and expectations for future experiments which involve neutralino-nucleus coherent processes are investigated. These results are compared to those obtained in a previous paper from indirect search data. In the present analysis particular attention is paid to the theoretical uncertainties due to the different estimates of the Higgs-nucleon coupling strength.

Minimal Supersymmetric Extension

In the context of the minimal supersymmetric extension of the Standard Model, we discuss the impact of the decays of the neutral Higgs bosons into supersymmetric particles, charginos/neutralinos and sfermions. We show that these decay modes could be dominant, when they are kinematically accessible, thus strongly suppressing the branching ratios for the decay channels which are used to detect the Higgs bosons at hadron colliders. These SUSY decay modes should therefore not be overlooked in the search for the Higgs particles at the LHC.
