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
In the target fragmentation region of Semi-Inclusive Deep Inelastic Scattering, the diffractively produced hadron has small transverse momentum. If it is at order of $\Lambda_{QCD}$, it prevents to make predictions with the standard collinear factorization. However, in this case, differential cross-sections can be predicted by the factorization with fracture functions, diffractive parton distributions. If the transverse momentum is much larger than $\Lambda_{QCD}$ but much smaller than $Q$ which is the virtuality of the virtual photon, both factorizations apply. In this case, fracture functions can be factorized with collinear parton distributions and fragmentation functions. We study the factorization up to twist-3 level and obtain gauge invariant results. They will be helpful for modeling fracture functions and useful for resummation of large logarithm of the transverse momentum appearing in collinear factorization.

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.
