Next-to-leading-order QCD corrections to gluon fragmentation into ${}^1{S}_0^{(1,8)}$ quarkonia

Feng Feng, Yu Jia

Within the NRQCD factorization framework, we compute the next-to-leading-order QCD corrections to the gluon fragmentation into the ${}^1{S}_0^{(1,8)}$ Fock components of a quarkonium…
