Inclusive gluon production in pion-proton collisions and the principle of maximum conformality renormalization scale

The contribution of the higher-twist mechanism to the large-p(T) inclusive gluon production cross section in pi p collisions is calculated in the case of the principle of maximum conformality and Brodsky-Lepage-Mackenzie approaches in the dependence of the pion distribution amplitudes. The higher-twist cross sections are obtained in the framework of the principle of maximum conformality and Brodsky-Lepage-Mackenzie approaches, and compared and analyzed in relation to the leading-twist cross sections and each other.
