Abstract
We search for the rare decay W+/- --> D-s(+/-) gamma in 82 pb(-1) of p (p) over bar collisions recorded with the Collider Detector at Fermilab. At the 95% confidence level, we find an upper limit on the relative branching fraction to be Gamma(W+/--->D-s(+/-) gamma)/Gamma(W+/--->e(+/-)nu)< 1.2 X 10(-2) [S0556-2821(98)50719-9].File in questo prodotto:
