Vv. Davidovsky et Bv. Struminsky, SMALL-X BEHAVIOR OF THE SINGLET COMPONENT G(1)(X) OF THE STRUCTURE-FUNCTION, Physics of atomic nuclei, 60(8), 1997, pp. 1348-1351
Within perturbative QCD, small-x asymptotic expressions for the single
t component g(l)(x) of the structure function are obtained for two cas
es: that of the exchange of two perturbative gluons and that of the ex
change of two nonperturbative gluons. A strong violation of the scalin
g behavior is predicted.
