23. One might expect intuitively that the emission of soft gluons would suppress the cross section, not enhance it. The physical cross section is expressed through the factorization theorem, Eq. (1). Part of the effect of the gluonic radiative corrections is included in the parton densities. The remainder is a positive enhancement in the partonic cross sections. For a general discussion of the reason for the positive signs, see N. Kidonakis and G. Sterman, in Les Rencontres de Physique de la Vallee d’Aoste, LaThuile, Aosta Valley, 1996, edited by M. Greco (Frascati, 1996), p. 333, hep-ph/9607222.
