Description
We study the diffractive production of back-to-back dijet at high $P_\perp$ in photon-nucleus collisions within the CGC framework. At leading order, this process exhibits TMD factorization, where the momentum imbalance between the jets is described by a diffractive gluon TMD distribution sensitive to gluon saturation. Next-to-leading-order corrections reveal a complex interplay of three distinct quantum evolutions of the diffractive gluon distribution, namely the BK/JIMWLK evolution, DGLAP evolution, as well as the Collins-Soper evolution. We demonstrate that the presence of the gluon saturation scale allows for both the boundary conditions and the complete CSS evolution to be computed entirely from first principles, without relying on non-perturbative inputs.
