Abstract

The present status of quark mixing and CP violation in the standard six quark model is reviewed in view of the recent experimental (b → u transition, B⁰ - B⁰ mixing, ε{lunate}′/ε{lunate}) and theoretical (progress in the calculation of the hadronic matrix elements) developments. Implications of the data on B⁰ - B⁰ mixing, ε{lunate} and ε{lunate}′/ε{lunate} for the value of the top quark mass (m_t) are discussed in detail. It is pointed out that m_t should not be too large for the standard model to be able to fit the recent NA31 data for ε{lunate}′/ε{lunate}. An upper bound for m_t is found as a function of various non-perturbative parameters. Typically m_t < 90 GeV is required. Implications of the B⁰ - B⁰ mixing for ε{lunate}′/ε{lunate} are also discussed.
