Abstract
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.
