摘要
in this work we analyze a new piece present in the Delta F = 2 effective Lagrangian in models with extra vector-like quarks. This piece, which was not taken into account previously, is required in order to preserve gauge invariance once the unitarity of the CKM matrix is lost. We illustrate the effects of this new piece in both, CP conserving and CP violating processes. (C) 1998 Elsevier Science B.V. All irghts reserved.
