Measuring Three Vector Boson Couplings in $qq\to qqW$ at the SSC

Abstract

We investigate the electroweak process $qq\to qqW$, {\it i.e.} $W$ production via $W{\hat{I}}^3$ and $WZ$ fusion, as a probe for nonstandard $WW{\hat{I}}^3$ and $WWZ$ vertices at hadron supercolliders. Triggering on events with one very forward and one very backward jet while requiring the $W$ decay lepton to be central, strongly enhances the triple gauge boson vertex contribution and suppresses backgrounds from QCD $Wjj$ events and $t\bar{t}j$ production below the signal level. At the SSC, the process is sensitive to $WWV$, $V={\hat{I}}^3,Z$ couplings $\hat{I}{º}_V-1$, $\hat{I}{»}_V$, and $g_1^Z$ in the $0.03\dots 0.1$ range.
