Abstract

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