Abstract

Results are given on a search for the decay W+/- --> pi+/--gamma with the UA2 detector in ppBAR collisions at square-root s = 630 GeV. No signal for such a process is observed and upper limits on the ratio R = GAMMA(W+/- --> pi+/--gamma)/GAMMA(W+/- --> e+/--nu) < 4.9 x 10(-3) and on the branching ratio BR(W+/- --> pi+/--gamma) < 5.4 x 10(-4) are derived at 95% confidence level.
