Dijet impact factor in DIS at next-to-leading order in the Color Glass Condensate

Abstract We compute the next-to-leading order impact factor for inclusive dijet production in deeply inelastic electron-nucleus scattering at small x Bj. Our computation, performed in the framework of the Color Glass Condensate effective field theory, includes all real and virtual contributions in t...
