Inclusive distributions are presented for final-state 7r° and 77° mesons produced in yp interactions. For photon energies from 50 to 130 GeV, both cross sections scale for fractional momenta #^0.30. The average transverse momentum for both mesons is approximately constant with energy and equal to 0.51 ±0.05 GeV/c at large x F . The 77%-° ratio similarly rises from 0.07±0.03 at x F =0.38 to 0.30±0.09 at x F =0.90. The 7T° distributions are in good agreement with those seen in the scattering of highly virtual incident photons.PACS numbers: 13.60.Le, 13.60.HbWe report on measurements of the inclusive production of ir° and 77 0 mesons in the interaction of photons of energies between 50 and 130 GeV with protons in a liquid hydrogen target. Our results are presented in terms of the square of the transverse momentum, p ± 2 , and of the fractional longitudinal momentum, x F . Our data span the region 0.2**p ± *z 1.5 GeV/c, and# F >0.30. Hence, they fall mainly within the photon fragmentation region.It is interesting to compare these data with prior results taken at lower incident photon energy, in order to check the accuracy of the scaling hypothesis for photoproduction. Another instructive comparison can be performed with inclusive distributions for reactions initiated by highly virtual photons. These are described in terms of a hardscattering process followed by quark fragmentation, 1 whereas real photon interactions are frequently thought of as the scattering of p, 00,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
