Abstract

We have determined constraints on the SU(5)C×SU(2)L×U(1)' model in terms of the extra mixing angle ϕ in the neutral gauge boson sector and ΔρM, the deviation of the Standard Model ρ parameter from unity at the tree level, using the recent precision measurements at LEP on electroweak parameters at the Z peak. The lower bound of the extra Z' boson mass has also been determined.
