Measurement of the $WWγ$ gauge boson couplings in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV
Abstract
Description
The $WWγ$ gauge boson couplings were measured using $p\bar{p}\to \ellνγ+X$ ($\ell=e,μ$) events at $\sqrt{s}=1.8$ TeV observed with the {DØ} detector at the Fermilab Tevatron Collider. The signal, obtained from the data corresponding to an integrated luminosity of $13.8 {\rm pb}^{-1}$, agrees well with the Standard Model prediction. A fit to the photon transverse energy spectrum yields limits at the 95% confidence level on the CP--conserving anomalous coupling parameters of $-1.6<Δκ<1.8$ ($λ$ = 0) and $-0.6<λ<0.6$ ($Δκ$ = 0).
