Semi-analytical calculation of gluon fragmentation into 1 S 0 [1,8] quarkonia at next-to-leading order

Semi-analytical calculation of gluon fragmentation into 1 S 0 [1,8] quarkonia at next-to-leading order

Abstract We calculate the NLO corrections for the gluon fragmentation functions to a heavy quark-antiquark pair in 1 S 0 [1] or 1 S 0 [8] state within NRQCD factorization. We use integration-by-parts reduction to reduce the original expression to simpler master integrals (MIs), and then set up diffe...
