摘要：

We consider models of maximal flavor violation, in which a new scalar mediates large q(3)<-> q(1) or q(3)<-> q(2) flavor-changing transitions (q(i) is an i'th generation quark), while q(3)<-> q(3) transitions are suppressed, e.g., xi(31), xi(13)similar to V-tb and xi(33)similar to V-td, where xi(ij) are the new scalar couplings to quarks and V is the Cabibbo-Kobayashi-Maskawa matrix. We show that, contrary to the conventional viewpoint, such models are not ruled out by the existing low-energy data on K-0, B-0 and D-0 oscillations and rare K and B-decays. We also show that these models of maximal flavor violation can have surprising new signatures at the LHC and the Tevatron.
