New neutral gauge bosons and new heavy fermions in the light of the new LEP data
We derive limits on a class of new physics effects that are naturally present in grand unified theories based on extended gauge groups, and in particular in E_6 and SO(10) models. We concentrate on i) the effects of the mixing of a new neutral gauge bosons with the standard Z_0; ii) the effects of a...
