Abstract
We calculate the next to leading (NLO) corrections to single and double
inclusive hadron production in Deep Inelastic Scattering (DIS) at small $x$ using
the Color Glass Condensate formalism. It is shown that all
UV and soft divergences cancel among various diagrams while the rapidity divergences lead to
JIMWLK evolution of dipoles and quadrupoles with rapidity. Finally the collinear divergences
are absorbed into parton-hadron fragmentation functions which lead to their DGLAP evolution
with $Q^2$.
