The process p̄p→evy+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 2 +2 6 and λ=0-1 8 +1 7 and their 95% confidence limits - 3 5 < κ < 5 9 and -3 6 < λ < 3 5 The results are model independent and in good agreement with the standard model values, κ=1 and λ=0. |
