Three-family top quark mass spectrum

摘要

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 B(sub d)--(bar B)(sub d) mixing, (vert bar)V(sub ub)/V(sub cb)(vert bar), B(sub K) and CP violation. Scatter distributions in (vert bar)V(sub ub)V(sub cb)(vert bar), (epsilon)(prime)/(epsilon) and x(sub s) vs m(sub t) 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.
