摘要: Abstract The effects at LEP and HERA are calculated of the second neutral gauge boson appearing in phenonenological superstring models with an effective SU(3) C ×SU(2) L ×U(1) Y R group. Present phenomenological constraints leave open possibility a measurable shift first Z mass, observable modifications to total e + − cross section forward-backward asymmetries peak beyond. High energy ep scattering assymetries may also differ significantly from standard model predictions.
