摘要：

We calculate gluon production in deep inelastic scattering of the current j = -1/4 F-mu nu(a) F-mu nu(a) off a large nucleus and in nucleon-nucleus collisions. In a covariant gauge calculation the transverse momentum spectrum of the gluon is determined by the final state interactions of the gluon with the nucleons in the nucleus. In a light-cone gauge calculation final state interactions are absent and these effects come from the light-cone wavefunction of the nucleus. We work in an approximation which neglects QCD evolution of gluons in the nucleon, that is in a quasi-classical approximation. (C) 1998 Published by Elsevier Science B.V.
