Abstract

We calculate the next-to-leading order corrections to single inclusive hadron production in deep inelastic scattering at small x using the color glass condensate formalism, for the case when the exchanged photon is transversely polarized. We show all UV and soft divergences cancel while collinear and rapidity divergences result in scale evolution of quark-hadron fragmentation function and small-x evolution of dipole amplitudes, respectively.
