19. We consider Eq. (4) in the LO of QCD in order to simplify the analysis because the factorized form of Eq. (4) cannot be realized in NLO, where we have double convolution integrals for parton distributions, fragmentation functions, and Wilson coefficents as discussed by G. Altarelli, R. K. Ellis, G. Martinelli, and S.-Y. Pi, Nucl. Phys. B160, 301 (1979)
