Sudakov double logs in single-inclusive hadron production in DIS at small $x$ from the Color Glass Condensate formalism (2406.08277v2)
Published 12 Jun 2024 in hep-ph
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 $\Lambda_{QCD}2 \ll \mathbf{p}_h2 \ll Q2$ kinematic regime where $\mathbf{p}_h$ 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.
