NLO CORRECTIONS TO THE WANDZURA-WILCZEK,
TWIST-3, NUCLEON DVCS AMPLITUDE FACTORIZE !
Kivel N., Mankiewicz L.
We computed the NLO corrections to twist-3, LT - flavor nonsinglet amplitude in DVCS on a nucleon in the
Wandzura-Wilczek approximation. Explicit
calculation shows that factorization holds for NLO contribution to this
amplitude, although the structure of the factorized amplitude at the
NLO is more complicated than in the leading-order formula.
