Inelastic and elastic photoproduction of J/Psi(3097)

Thesis/Dissertation ·
OSTI ID:6259074
The J/Psi(3097) photoproduction cross section on hydrogen has been measured at a mean photon energy of 103 GeV, using the Fermilab Tagged Photon Spectrometer, Batavia, Illinois. The total cross section, 21.5 +/- 2.4 nb (+/- 25% normalization) has been subdivided into 7 categories: 1) all events, 2) forward elastic, 3) forward inelastic, 4) recoil inelastic, 5) totally elastic, 6) inelastic, and 7) inelastic with z = E/sub Psi//E/sub ..gamma../ < .9, as defined in the text. The forward inelastic cross section observed in this experiment is much smaller than that seen in muoproduction experiments (16, 17), but is roughly consistent with second order perturbative QCD predictions (5). The mean p/sub +/ of the forward inelastic events is significantly larger than that of the totally elastic events, in accord with muoproduction experiments as well as the second order QCD predictions.
