Abstract

The ratio Δm_K/m_K within the standard model with 3 generations is calculated as a function of the CP nonconserving phase δ₁₃ and the quark masses m_c,m_t assuming the current values of the Cabibbo-Kobayashi-Maskawa mixing angles. We have found that varying δ₁₃ and m_c within the allowed range, not all the values for the top quark mass fit the experimental value for that ratio.
