$W\gamma$ and $Z\gamma$ Production at Tevatron

Abstract

We present results from CDF and DØ on $W\gamma$ and $Z\gamma$ productions in $p\bar{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}.$ The goal of the analyses is to test the non-abelian self-couplings of the $W$, $Z$ and photon, one of the most direct consequences of the $SU(2{)}_L\otimes U(1{)}_Y$ gauge symmetry. We present direct measurements of $WW\gamma$ couplings and limits on $ZZ\gamma$ and $Z\gamma \gamma$ couplings, based on $p\bar{p}\to \ell \nu \gamma +X$ and $p\bar{p}\to \ell \ell \gamma +X$ events, respectively, observed during the 1992--1993 run of the Fermilab Tevatron Collider.
