Pj. Sutton et al., PARTON DISTRIBUTIONS FOR THE PION EXTRACTED FROM DRELL-YAN AND PROMPTPHOTON EXPERIMENTS, Physical review. D. Particles and fields, 45(7), 1992, pp. 2349-2359
We determine the parton distributions of the pion from a consistent ne
xt-to-leading-order analysis of several high-statistics pi +/- N exper
iments including both Drell-Yan and prompt photon production.
