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.
