Hard Hadron-Nucleus Processes and Multiquark Configurations in Nuclei

摘要

The inclusive large Psub(perpendicular) hadron production in (pA) reactions is investigated. It is shown that the difference between quark distributions in free nucleon and in a nucleus can give the anomalously large emission of hadrons - in particular mesons - at x sub(perpendiclar) = 2Psub(perpendiclar) / sqrt S > or approximately 0-7-0.8 that is confirmed by experiment. Multiple quark collisions inside the nucleus give the main contribution into considered spectra at smaller x sub(perpendicular). 26 refs.; 3 figs. (Atomindex citation 17:057304)
