Large time-dependent CP violation in the Bs0 system and finite D0-(D)over-bar0 mass difference in a four generation standard model

Combining the measured B-s mixing with b -> s center dot(+)center dot(-) rate data, we find a sizable 4 generation t(') quark effect is allowed, for example, with m(t)(')similar to 300 GeV and V(t)(')s(*)V(t)(')b similar to 0.025e(+/- i70 degrees), which could underlie the new physics indications in CP violation studies of b -> s (q) over barq transitions. With positive phase, large and negative mixing-dependent CP violation in B-s system is predicted, sin2 Phi(Bs)similar to-0.5 to -0.7. This also can be probed via width difference methods. As a corollary, the short distance generated D-0-(D) over bar (0) mass difference is found to be consistent with, if not slightly higher than, recent B factory measurements, while CP violation is subdued with sin2 Phi(D)similar to-0.2.
