摘要
The probability of possible values for the four angles of the CKM matrix are determined by finding the chi(2) values for each choice of angles fitting to ten standard experiments. The chi(2) isosurface plots are first displayed in the space of three of the CKM angles showing the dependence of the bounds on delta and greatly improving the lower bound on V-cb. The maximum likelihood chi(2) contour plot in the rho/eta plane shows the probability of each location for the vertex of the unitarity triangle which controls CP-violating asymmetries in B-0 decays. We find for m(t) = 150 GeV that at the 2 sigma level the signal for asymmetries measuring sin(2 beta) is at least sin(2 beta) greater than or equal to 0.25. At the 1 sigma level the signal is at least sin(2 beta) greater than or equal to 0.40, with the preferred range of sin(2 beta) = 0.6 +/- 0.2.
