Gluon fragmentation into 3 P J 1 8 $$ {P}_J^{\left[1,8\right]} $$ quark pair and test of NRQCD factorization at two-loop level

Abstract The next-to-leading order (NLO) ( O $$ \mathcal{O} $$ ( α s 3 $$ {\alpha}_s^3 $$ )) corrections for gluon fragmentation functions to a heavy quark-antiquark pair in 3 P J 1 8 $$ {P}_J^{\left[1,8\right]} $$ states are calculated within the NRQCD factorization. We use the integration-by-parts...
