## Abstract

We find the domain of the values of m_{t}, τ_{B} and R (the top quark mass, the B-meson lifetime and γ(b → u)/γ(b → c) respectively) for which the standard six-quark model is consistent with the observed CP violation in the kaon system and with the recent experimental results for B-meson decays. The mixing angles θ_{2}, θ_{3}, the phase δ and the ratio ε{lunate}′/ε{lunate} are calculated as functions of m_{t}, τ_{B} and R. The sensitivity of the analysis to the variation of the "bag" parameter B and the b- and c-quark masses is investigated. Two types of calculations are presented: one which takes into account the K_{L}-K_{S} mass difference and the other one which ignores it. We discuss the implications of a possible discovery of a top quark with m_{t} below 30 GeV and we point out that for B ≤ 1 3 and m_{t} ≈ O(25 GeV) a simultaneous consistency of the standard model with the data for τ_{B}, R, ε{lunate} and ε{lunate}′/ε{lunate} cannot be achieved. Furthermore for B ≤ 2 3 and m_{t} ≤ 35 GeV we find ε{lunate}′/ε{lunate} ≥ 0.01. No interesting upper bound on m_{t} follows from K_{L} → μμ.
