摘要：

We evaluate the Zl+l- cross section at present and future hadron colliders, for the minimal (E6) extended electroweak models inspired by superstrings (including renormalization effects on new gauge couplings and new mixing angles). Popular models are discussed for comparison. Analytical expressions for the bounds on the mass of a new gauge boson, MZ, as a function of the bound on the ratio R(Z)B(Zl+l-)(Z)B(Zl+l-), are given for the CERN Spp»S, Fermilab Tevatron, Serpukhov UNK, CERN Large Hadron Collider, and Superconducting Super Collider for the different models. In particular, the MZ bounds from the present R limit at CERN, as well as from the eventually available R limits at Fermilab and at the future hadron colliders (after three months of running at the expected luminosity), are given explicitly. © 1990 The American Physical Society.
