### Applications of Lipatov's high energy effective action to NLO BFKL jet phenomenology.

Martin Hentschinski, Beatrice Murdaca & Agustin Sabio Vera
We report on recent progress in the evaluation of next-to-leading order observables using Lipatov's QCD high energy effective action. We calculate both real and virtual corrections to the quark induced forward jet vertex at NLO, making use of a new regularization method and a subtraction mechanism. As a new result we determine the real part of the NLO Mueller-Tang impact factor which is the only missing element for a complete NLO BFKL description of dijet...
