Limits on anomalous WWγ couplings from pp → Wγ + X events at √s = 1.8 TeV

Published

Journal Article

We have measured the WW? gauge boson coupling parameters using pp → 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 pp → Wγ+ X with pγT> 10 GeV/c and Rℓν> 0.7 is 11.3+1.7-1.5±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 < Δκ < 0.94 and -0.31 < λ < 0.29. Similar limits are set on the CP-violating coupling parameters. © 1997 The American Physical Society.
