Abstract
We have measured the WWγ gauge boson coupling parameters using p\n¯\np→ℓνγ+X ( ℓ=e,μ) events at √s=1.8 TeV. The data, corresponding to an integrated luminosity of 92.8pb−1, were collected using the DØ detector at the Fermilab Tevatron Collider. The measured cross section times branching ratio for p\n¯\np→Wγ+X with p\nγ\nT&gt;10 GeV/c and Rℓγ&gt;0.7 is 11.3\n+1.7\n−1.5±1.5 pb, in agreement with the standard model prediction. The 1 degree of freedom 95% confidence level limits on individual CP-conserving parameters are −0.93&lt;Δκ&lt;0.94 and −0.31&lt;λ&lt;0.29. Similar limits are set on the CP-violating coupling parameters.

It is shown that although good fits can be obtained with or without this symmetry breaking, more physically reasonable parton distributions are obtained if the authors allow [ital] [bar d]][gt][ital [bar u] at small [ital x], and with the inclusion of the latest deep-inelastic data.
