Title: Weak-interaction models with new quarks and right-handed currents

We discuss various weak-interaction issues for a general class of models within the SU(2) x U(1) gauge-theory framework, with special emphasis on the effects of right-handed charged currents and of quarks bearing new quantum numbers. In particular we consider the restrictions on model building which are imposed by the small K/sub L/--K/sub S/ mass difference and by the $delta$I = 1/2 rule, and we classify various possibilities for neutral current interactions and, in the case of heavy mesons with new quantum numbers, various possibilities for mixing effects analogous to K/sub L/--K/sub S/ mixing.
