Implications of high precision experiments and the CDF top quark candidates

There is now enough data to perform more general fits to parameters describing new physics effects and to separate these from {ital m}{sub {ital t}} and {ital M}{sub {ital H}}. Allowing the parameter {rho}{sub 0}, which describes sources of SU(2) breaking beyond the standard model, to be free one finds {rho}{sub 0}=1.0012{plus_minus}0.0017{plus_minus}0.0017, remarkably close to unity. One can also separate the new physics contributions to the oblique parameters {ital S}{sub new}, {ital T}{sub new}, and {ital U}{sub new}, which all take values consistent with zero. The effects of supersymmetry on the determination of the standard model parameters are discussed.
