  • We propose a new approach to treat the nucleon structure in terms of an effective chiral Lagrangian. The state vector of the nucleon is defined on the light front plane and is decomposed in Fock components. An adequate Fock sector dependent renormalization scheme is applied. We present our first results of the calculation of nucleon properties in a two-body Fock truncation.

  • We study the neutralino relic density in the minimal supersymmetric standard model with natural light Higgs sector in which all Higgs masses, the supersymmetry (SUSY) breaking parameters, and the Higgsino mass parameter {mu} are of order the weak scale. To realize this situation we adopt nonuniversal Higgs masses at the grand unified scale. We show that in some parameter space in which the SUSY breaking parameters are comparatively small, not only the constraint from the observed relic density of dark matter but also the LEP Higgs bound and the constraint from the b{yields}s{gamma} process are satisfied. In most of themore » parameter space, the neutralino relic density becomes smaller than the observed relic density in contrast with the results in the constrained minimal SUSY standard model (CMSSM). The reason is that the neutralino coannihilation processes to Higgs bosons open even if the gaugino mass is small and the cross sections become large due to the small dimensionful parameters. Especially the small {mu} parameter and the light CP-odd Higgs, which are difficult to be realized in the CMSSM, are essential for the result.« less
