On the mass and mixings of the ZE
Description
The experimental data on the neutral current couplings are used to derive lower bounds on the mass of ZE, the extra neutral gauge boson appearing in the minimal 'beyond the standard model' scenario favoured in superstring compactifications. This is based on the gauge group SU(3)cxSU(2)LxU(1)YxU(1)E. Taking sin2θw = 0.229, mW = 80.76 GeV and mZ = 91.59 GeV it is found that the mixing angle θ between Z and ZE must satisfy -0.136 < sinθ < -0.007 corresponding to mZe > 152 GeV or, assuming E6 unification mZe > 155 GeV.
