Gluonic nucleon energy correlators in the CGC reduce at eikonal accuracy to the unpolarized and linearly polarized gluon components, both given by the adjoint dipole S-matrix, and the linearly polarized one drives a saturation-sensitive cos 2phi asymmetry in DIS.

abstract
We study the inclusive production of two hadrons in deep inelastic processes, l N ---> l h_1 h_2 X, with h_1 in the current fragmentation region (CFR) and h_2 in the target fragmentation region (TFR). Assuming a factorized scheme, the recently introduced polarized and transverse momentum dependent fracture functions couple to the transverse momentum dependent fragmentation functions. This allows the full exploration of the fracture functions for transversely polarized quarks. Some particular cases are considered.

Gluonic nucleon energy correlators and fracture functions for Color Glass Condensate
Gluonic nucleon energy correlators in the CGC reduce at eikonal accuracy to the unpolarized and linearly polarized gluon components, both given by the adjoint dipole S-matrix, and the linearly polarized one drives a saturation-sensitive cos 2phi asymmetry in DIS.
