Measurement of the cross section for γγ→pp̄
A measurement of the cross section for γγ→pp̄ is performed at two-photon center-of-mass energies between 2.00 and 3.25 GeV. These results are obtained using e+e-→e+e-pp̄ events selected from 1.31 fb-1 of data taken with the CLEO II detector. The measured cross section is in reasonable agreement with previous measurements and is in excellent agreement with recent calculations based on a diquark model. However, leading order QCD calculations performed using the Brodsky-Lepage formalism are well below the measured cross section. © 1994 The American Physical Society.
