  In this conference report a summary is given on the theoretical work that has
contributed to provide accurate theoretical predictions for testing the
standard model in present and future experiments. Precision calculations for
the vector boson masses, for the Z resonance, W pair production, and for the
g-2 of the muon are reviewed and the theoretical situation for the Higgs sector
is summarized. The status of the standard model is discussed in the light of
the recent high and low energy data. New Physics beyond the standard model is
briefly addressed as well, with special emphasis on the minimal supersymmetric
standard model. A few references have been added.
