Gluon fragmentation into quarkonium at next-to-leading order using FKS subtraction

Abstract We present the calculation at next-to-leading order (NLO) in α s of the fragmentation function of a gluon into heavy quarkonium in the color-octet spin-singlet S-wave channel. To calculate the real NLO corrections, we adapt a subtraction scheme introduced by Frixione, Kunszt, and Signer. Ul...
