In this paper, we investigate the next-to-leading order contribution of the higher-twist Feynman diagrams to the large-pT inclusive pion production cross-section in proton–proton collisions and present the general formulae for the higher-twist differential cross-sections in the case of the running coupling and frozen coupling approaches. We compared the resummed next-to-leading order higher-twist cross-sections with the ones obtained in the framework of the frozen coupling approach and leading-twist cross-section. The structure of infrared renormalon singularities of the higher-twist subprocess cross-section and its resummed expression (the Borel sum) are found. It is shown that the resummed result depends on the choice of the meson wave functions used in the calculations. We discuss the phenomenological consequences of possible higher-twist contributions to the meson production in proton–proton collisions in next-to-leading order at RHIC.

We calculate the "naive nonabelianization" (NNA) contributions of the higher-twist Feynman diagrams to the large-pT inclusive pion production cross-section in proton–proton collisions in the case of the running coupling and frozen coupling approaches. We compare the resummed "naive nonabelianization" higher-twist cross-sections with the ones obtained in the framework of the frozen coupling approach and leading-twist cross-section. The structure of infrared renormalon singularities of the higher-twist subprocess cross-section and it's resummed expression are found. We discuss the phenomenological consequences of possible higher-twist contributions to the pion production in proton–proton collisions in within NNA.
