ABSTRACT: We determine both real and virtual next-to-leading order corrections to the
gluon induced forward jet vertex, from the high energy effective action
proposed by Lipatov. For these calculations we employ the same regularization
and subtraction formalism developed in our previous work on the quark-initiated
vertex. We find agreement with previous results in the literature.

ABSTRACT: Lipatov's high-energy effective action is a useful tool for computations in
the Regge limit beyond leading order. Recently, a regularisation/subtraction
prescription has been proposed that allows to apply this formalism to calculate
next-to-leading order corrections in a consistent way. We illustrate this
procedure with the computation of the gluon Regge trajectory at two loops.

ABSTRACT: We investigate dijet production at large rapidity separation in QCD and N = 4
SYM, showing that both theories give similar predictions for observables only
sensitive to conformal properties of the scattering such as ratios of azimuthal
angle correlations. Renormalization prescriptions are important in this
comparison.
