Models with new vector-like quarks can produce observable quark mixingeffects which are forbidden in the Standard Model. We classify all such modelsand write down the effective Lagrangian that results from integrating out thenew quarks. We study the relations between neutral and charged currents anddiscuss how to distinguish among the different possibilities.Comment: 15 pages, 1 figure, typos corrected, version to appear in JHE
