| heal.abstract | The predictions of the MSSM are discussed in the light of recent LEP and SLD precision data. The full supersymmetric one-loop corrections to the effective weak mixing angle are considered. Potentially dangerous, large logarithmic sparticle corrections are cancelled. The relative difference factor Delta k between the mixing angle defined as a ratio of couplings and the experimentally obtained angle is discussed and it is found that Delta k is dominated by the oblique corrections, while the non-oblique overall supersymmetric EW and SQCD corrections are negligible. We also reconsider the next to minimal supersymmetric standard model (NMSSM) as a natural solution to the mu problem and show that both the stability and the cosmological domain wall problems are eliminated if we impose a discrete Z(2) R-symmetry on the non-renormalizable operators of the theory. | en |
