description

Abstract We analyse the restrictions on the mass and the mixing of an additional Z′ gauge boson that follow from the recent LEP measurements taking into account standard model (SM) radiative corrections. We find that these restrictions depend sharply on the assumed values for the SM structural parameters, the most important of which are M w and m top . The constraints become stronger for lighter W and heavier top.
