Abstract
We search for the rare decay W+/- --> gammapi+/- in 4.2 pb-1 of ppBAR collisions recorded with the Collider Detector at Fermilab. At the 95% confidence level, we find an upper limit on the partial decay width to be GAMMA(W+/- --> gammapi+/-)/GAMMA(W+/- --> e+/- nu) less-than-or-equal-to 7.5 x 10(-3).File in questo prodotto:
