摘要：

We develop an effective lagrangian based framework for the inclusion of new heavy physics effects on gauge boson self-energies, various observables may be expressed in terms of the parameters S, T and U. We then generalize this framework to include a new U (1) gauge boson. We treat the effects of mixing through kinetic terms with the Z and the photon as well as mass mixing with the Z. We show how the bulk of these effects produce effective shifts in the parameters S, T and U.
