NLO Impact Factor for Inclusive Photon+Dijet Production in e + A DIS at Small x

We summarize the results of a recent first computation in the Color Glass Condensate effective field theory (CGC EFT) of the next-to-leading order (NLO) impact factor for inclusive photon+dijet production in electron-nucleus (e+A) deeply inelastic scattering (DIS) at small x. Our computation simultaneously provides the ingredients to compute fully inclusive DIS, inclusive photon, inclusive dijet and inclusive photon+jet channels to the same accuracy. We outline the Wilsonian renormalization group (RG) procedure by virtue of which extant results for the next-to-leading log (in x) JIMWLK evolution, can be integrated with our results to improve the precision to $O\left({\alpha }_s^3\ln \left(1/x\right)\right)$ accuracy. This paves the way towards quantitative studies of saturation at a future Electron-Ion Collider.
