Abstract

We present a search for the decay W^±→π^±γ, using data taken at the CERN proton-antiproton Collider with the UA1 detector and corresponding to an integrated luminosity of 0.7 pb^-1. We do not observe a signal for such a process: hence we obtain an upper limit on the π^±γ decay width of 5.8×10^-2Γ (W^±→e^±v) (95%CL).
