Form factors and radiative Corrections in Z' Physics

This lecture contains a pedagogical approach to the description of Z’ physics in the formalism of form factors. Usually, only electroweak corrections are described by form factors, which modify the Weinberg angle and the overall normalization. It is demonstrated how this formalism can be extended to include different Born contributions. In the second part of the lecture, QCD and QED corrections are considered. The development and consequences of the radiative tail for a Z’ search are discussed in detail.
