Title: Search for the rare decay W{sup {plus_minus}}{r_arrow}D{sub s}{sup {plus_minus}}{gamma} in p{bar p} collisions at {radical} (s) =1.8thinspTeV

We search for the rare decay W{sup {plus_minus}}{r_arrow}D{sub s}{sup {plus_minus}}{gamma} in 82thinsppb{sup {minus}1} of p{bar p} collisions recorded with the Collider Detector at Fermilab. At the 95{percent} confidence level, we find an upper limit on the relative branching fraction to be {Gamma}(W{sup {plus_minus}}{r_arrow}D{sub s}{sup {plus_minus}}{gamma})/{Gamma}(W{sup {plus_minus}}{r_arrow}e{sup {plus_minus}}{nu}){lt}1.2{times}10{sup {minus}2}. {copyright} {ital 1998} {ital The American Physical Society}
