Production and signature of intermediate vector bosons

Journal Article · · Ann. Phys. (N.Y.); (United States)
The front-back asymmetriy of outgoing muons in the inclusive reaction pp-bar..-->..Z (..--> mu../sup +/..mu../sup -/)+ anything is calculated in the framework of the Drell--Yan model. We get very general expressions for the front-back asymmetry and the differential cross section in terms of the weak coupling constants and the parton distributions. Results for W +- production and proton-proton collisions are given. Numerical estimates are made using various parton distributions and the Weinberg-Salam model for definiteness. We comment on the predictions of gauge theories that accommodate the absence of parity violating effects in atomic physics. We also give a new estimate of the inclusive cross section pp-bar or pp..-->..Z (..--> mu../sup +/..mu../sup -/) or W +- (..--> mu../sup plus-or-minusnu/..mu..)+ anything. The effects of asymptotic freedom in the front-back asymmetries and the total cross sections are investigated. We reanalyze results for the purely leptonic reaction e/sup +/e/sup -/..--> gamma..,Z..--> mu../sup +/..mu../sup -/.
