Momentum Conservation at Small x
arXiv:hep-ph/9507321 · doi:10.1016/0370-2693(95)01090-D
Abstract
We discuss how momentum conservation is implemented in perturbative computations based on expansions of anomalous dimensions appropriate at small $x$. We show that for any given choice of $F_2$ coefficient functions there always exists a factorization scheme where the gluon is defined in such a way that momentum is conserved at next to leading order.
