Description

Recently obtained bounds on the mass of the new neutral gauge bosons in E6 models using data from SN 1987A are reexamined and improved by the incorporation of Z-Z' mixing effects and radiative corrections. The sensitivity of these bounds to the various model parameters, e.g., the ratio of Higgs vacuum expectation values (tanβ), is examined and, in some models, the value of tanβ can change the resulting Z' mass bound by more than 400--600 GeV
