Abstract

Following a previous study of the one-loop factorization of the nonsinglet g2 structure function of the nucléon, we present in this paper the next-to-leading order coefficient functions in the singlet sector. To obtain the result, the partonic processes of virtual Compton scattering off two and three on-shell gluons are calculated. A key step in achieving the correct factorization is to separate the correct twist-two contribution. The BurkardtCottingham sum rule is nominally satisfied at this order. X
