Abstract

We investigate the high Q² (photon virtuality) limit of single-inclusive hadron production in DIS (SIDIS) at small x, using the color glass condensate formalism at next-to-leading order. We focus on the Λ_QCD² ≪ p_h² ≪ Q² kinematic regime where p_h is the produced hadron transverse momentum, and extract the Sudakov double logarithms. We further argue that compatibility between the CGC calculation and TMD factorization at one-loop order can only be achieved if the small-x evolution is kinematically constrained.
