摘要

The short-distance coefficients for the color-octet S-3(1) term in the fragmentation function for a gluon to split into heavy quarkonium states is calculated to order alpha(s)(2). The gauge-invariant definition of the fragmentation function by Collins and Soper is employed. Ultraviolet divergences are removed using the MS renormalization procedure. The longitudinal term in the fragmentation function agrees with a previous calculation by Beneke and Rothstein. The next-to-leading order correction to the transverse term disagrees with a previous calculation, (C) 2000 Elsevier Science B,V. All rights reserved. [References: 15]
