摘要：

We have calculated the NLO corrections to the twist-2 part of the deeply-virtual Compton scattering amplitude, Our results for the transverse and antisymmetric parts agree with recent calculations by Ji and Osborne and by Belitsky and Muller. Ln addition we present NLO results for the longitudinal part of the amplitude. (C) 1998 Elsevier Science B.V. All rights reserved.
