Of the many ingredients of the Standard Model that are relevant for the analysis of CP asymmetries in B{sup 0} decays, some are likely to hold even beyond the Standard Model while other are sensitive to new physics. Consequently, certain predictions are maintained while other may shoe dramatic deviations from the Standard Model. Many classes of models may show clear signatures when the asymmetries are measured: four quark generations, Z-mediated flavor changing neutral currents, supersymmetry and real superweak'' models. On the other hand, models of left-right symmetry and multi-Higgs sectors with natural flavor conservation are unlikely to modify the Standard Model predictions.
