Dark Matter Relic Density

In supercritical string cosmology (SSC), a time-dependent dilaton leads to a smoothly evolving dark energy and modifies the regions of the mSUGRA parameter space where the observed value of the dark matter relic density may be obtained. In particular, the dilaton dilutes the supersymmetric dark matter density (of neutralinos) by a factor [Formula: see text] and consequently relaxes the allowed parameter mSUGRA parameter space. The final states expected at the LHC in this scenario, consist of Z bosons, Higgs bosons, and/or high energy taus. From this, it is possible to characterize these final states and determine the model parameters. Using these parameters, we determine the dark matter content and the neutralino–proton cross section. All these techniques can also be applied to determine model parameters in SSC models with different SUSY breaking scenarios.

The Universe

In the gauge-Higgs unification the 4D Higgs field becomes a part of the extra-dimensional component of the gauge potentials. In the SO(5) × U(1) gauge-Higgs unification in the Randall-Sundrum warped spacetime the electroweak symmetry is dynamically broken through the Hosotani mechanism. The Higgs bosons become absolutely stable, and become the dark matter of the universe. The mass of the Higgs boson is determined from the WMAP data to be about 70 GeV.

Interpretation Of Results

The questions of implementation in the theory of few Higgs bosons is consid- ered in this article. The corresponding hypothesis, which are the consequences of interpretation of results of LHC-experiments are experienced. Arguments in fa- vor of supersymmetric models are presented. Within the frameworks of NMSSM, estimates for the areas of variation of free parameters of the model are made, masses of Higgs bosons and neutralino, which is a candidate for dark matter particles are calculated. The values of these physical quantities collected in a specific set can be combined in the so-called scenario study of Higgs boson. Four scenarios in which there is an explanation of existing hypotheses are revealed.
