Abstract

We have made a systematic search for direct e+ and e- production in p-p and p-Be collisions at 12 GeV/c incident proton momentum. Data were collected at c.m. angles of 20A°, 35A°, 63A°, and 84A°. We find no evidence for the previously reported rise in the ratio eπ at low momentum transfer. The data are consistent with zero direct electron production from other than previously known sources.
