Abstract
We report on the production of e(+/-)mu(-/+) pairs in 450 GeV/c pBe co llisions at the CERN SPS. The e mu signal, which has average missing e nergy of 21 GeV, is shown to be consistent with expectations from char m decay, and implies a sigma x B for <c(c)over bar> production in p-nu cleon collisions of 0.63 +/- 0.35 mu b. Alternatively, using an estima te of charm production from other experiments, the data imply a 95% co nfidence level upper limit of 1.16 mu b on any new physics process whi ch produces e(+/-)mu(-/+).
