Description

We expand upon our previous Monte-Carlo-type study of 3-family mass matrices which lead to the experimentally-determined KM matrix and satisfy the constraints imposed by Bd--bar Bd mixing, |Vub/Vcb|, BK and CP violation. Scatter distributions in |VubVcb|, ε'/ε and xs vs mt are presented for the standard minimal Higgs structure as well as top quark mass histograms for the minimal and 2-doublet Higgs models. A top quark mass in the range of 100--200 GeV is strongly favored with all the constraints imposed, but if the lower bound on the CP-violating J-value is completely relaxed, a secondary probability peaking occurs in the mass histograms which lies above 220 GeV in the minimal Higgs model. 19 refs., 5 figs
