Search for Z(prime) and W(prime) at CDF

摘要

We have searched for heavy neutral and charged gauge bosons via the decays Z(prime) (yields) ee and W(prime) e(nu) in (bar p)p collisions at (radical)s = 1.8 TeV. The data were obtained using the CDF detector during 1992--1993 run corresponding to an integrated luminosity of 19.7(plus minus)0.7 pb(sup (minus)1). We present a 95% confidence level upper limit on the production cross section times branching ratio of Z(prime) and W(prime) as a function of Z(prime) and W(prime) mass. Assuming Standard Model coupling strengths, we exclude a Z(prime) with mass less than 505 GeV/c(sup 2) and a W(prime) with mass less than 652 GeV/c . We also present lower mass limits for Z(prime) bosons from E(sub 6) models and the Alternative Left-Right Model.
