Abstract:

The process pp→evγ+X is studied as √s=630 GeV. The observed signal is used to extract a direct measurement of the parameters κ and λ which define the magnetic dipole and electric quadrupole moments of the W boson and therefore the WWγ coupling. We find κ=1+2.6-2.2 and λ=0+1.7-1.8 and their 95% confidence limits -3.5<κ<5.9 and -3.6<λ<3.5. The results are model indepedent and in good agreement with the standard model values, κ=1 and λ=0. © 1992.

Abstract:

Results are given on a search for the decay W±→π±γ with the UA2 detector in pp collisions at √s=630 GeV. No signal for such a process is observed and upper limits on the ration R=Γ(W±→π±γ)/ Γ(W±→e±v)<4.9× 10-3 and on the branching ratio BR(W±→π±γ)<5. 4×10-4 are derived at 95% confidence level. © 1992.
