Title: Search for the rare decay W{sup {plus_minus}}{r_arrow}{pi}{sup {plus_minus}}+{gamma} in proton-antiproton collisions at {radical}(s) =1.8 TeV

Search for the rare decay W{sup {plus_minus}}{r_arrow}{pi}{sup {plus_minus}}+{gamma} in proton-antiproton collisions at {radical}(s) =1.8 TeV We have searched for the rare decay W{sup {plus_minus}}{r_arrow}{pi}{sup {plus_minus}}+{gamma} in 83 pb{sup {minus}1} of data taken in proton-antiproton collisions at {radical}(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{plus_minus}1.5 events. We set a 95{percent} confidence level upper limit of 7{times}10{sup {minus}4} on the ratio of partial widths, {Gamma}(W{sup {plus_minus}}{r_arrow}{pi}{sup {plus_minus}}+{gamma})/{Gamma}(W{sup {plus_minus}}{r_arrow}e{sup {plus_minus}}+{nu}). {copyright} {ital 1998} {ital The American Physical Society}
