Basic Parameters and Some Precision Tests of the Standard Model

Abstract

We present a review of the masses (except for neutrino masses) and interaction strengths in the standard model. Special emphasis is put on quantities that have been determined with significantly improved precision in the last few years. In particular, a number of determinations of ${\alpha }_s$ and the electromagnetic coupling on the $Z$, ${\alpha }_{\mathrm{QED}}(M_Z^2)$ are presented and their implications for the Higgs mass discussed; the best prediction that results for this last quantity being $$M_H=102_{-36}^{+54}GeV/c^2.$$ Besides this, we also discuss a few extra precision tests of the standard model: the electron magnetic moment and dipole moment, and the muon magnetic moment.
