Abstract

The production of electron-positron pairs of masses below 1200 MeV/c2 and of transverse momentum above 1.8 GeV/c has been studied in pp collisions at √s = 53 and 63 GeV. The cross section for ϱ, ω, and φ production are presented. The continuum below 600 MeV/c2 is consistent with origination from Dalitz decays of η and ω mesons and from semileptonic decay of D and D mesons.
