Momentum conservation at small x
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...

| Sumario: | 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. |
