Abstract

We have searched for the rare decay W+/- --> pi(+/-) + gamma in 83 pb(-1) of data taken in proton-antiproton collisions at root s = 1.8 TeV with the Collider Detector at Fermilab. We find three events in the signal region and estimate the background to be 5.2+/-1.5 events. We set a 95% confidence level upper limit of 7 x 10(-4) on the ratio of partial widths, Gamma(W+/- --> pi(+/-) + gamma)/Gamma(W+/- --> e(+/-) + nu). [S0556-2821(98)50115-4]
