We present results for the NLO kernel of the BKP equations for composite states of three reggeized gluons in the Odderon channel, both in QCD and in N=4 SYM. The NLO kernel consists of the NLO BFKL kernel in the color octet representation…

More than 25 years ago, Mueller Navelet jets were proposed as a decisive test of BFKL dynamics at hadron colliders. We here study this process at NLL BFKL accuracy, taking into account NLL corrections to the Green's function and to the jet…

We show that the gluon of N=4 Yang--Mills theory lies on a Regge trajectory, which then implies that the graviton of N=8 supergravity also lies on a Regge trajectory. This is consistent with the conjecture that N=8 supergravity is…
