Description

An SU(2) consistent introduction of particular flavor changes in the neutral current of a generalized Weinberg-Salam model for hadrons is described and examples are discussed, in particular, two CP-violating and flavor-changing five-quark models, which are in agreement with measurements on the K0-K-bar0 and theD0-D-bar0 system and still allow t bold-arrow-left-right c and b bold-arrow-left-right s transitions. The evidence for the strong suppression of a neutral u bold-arrow-left-right c transition from D0-D-bar0 measurements is briefly reviewed. The experimental signatures of the different flavor changes, to be detected or to be ruled out in the future, are discussed
