Abstract
Inspired by a recent study by Iancu, Mueller, and Triantafyllopoulos [Phys. Rev. Lett. 128, 202001 (2022)], we propose semi-inclusive diffractive deep inelastic scattering (SIDDIS) to investigate the gluon tomography in the nucleon and nuclei at small $x$. The relevant diffractive quark and gluon parton distribution functions (DPDFs) can be computed in terms of the color dipole $S$-matrices in the fundamental and adjoint representations, respectively.
