Abstract

We report a measurement of the e+e-e+e-pp+- process with the TPC/Two-Gamma facility at the PEP e+e- storage ring at SLAC. Forty-five pp+- events were identified in data corresponding to an integrated e+e- luminosity of 142 pb-1. The cross section for pp+- is given both as a function of the center-of-mass energy W, with W between 2.5 and 5.5 GeV, and as a function of the in variant mass squared q2 of one of the photons, with -q2<7 GeV2. This cross section falls much less rapidly with W than does the cross section for a similar process, pp. No 00 production is observed, and only a small fraction of the events at low W is consistent with ++- , ++p-, or - p+. In an expanded search through the same data, four events compatible with either (p-) or 0(0) production were found.
