Abstract (data abstract)
CERN-LEP. Measurement of the cross sections for two photon exclusive production of proton-antiproton pairs in E+ E- collisions at centre-of-mass energies from 183 to 209 GeV. The data cover the two photon W range 2.1 to 4.5 GeV, and have an integrated luminosity of 667 pb-1.
