Description
We discuss evolution of the small-x gluon helicity operator in the rapidity factorization approach. The operator is constructed from a polarized Wilson line with one non-eikonal local operator insertion and gives rise to gluon helicity TMDs at small x. To obtain the evolution equation for this operator we employ the background field method and derive the form of the leading sub-eikonal correction to the gluon propagator in the background-Feynman gauge. We also discuss relation to the large-x polarized DGLAP evolution.
