High-energy resummed Higgs-plus-jet distributions at NLL/NLO* with POWHEG+JETHAD

Abstract

We study the inclusive production, at hadron colliders, of a Higgs boson and a jet widely separated in rapidity. Kinematic sectors explored fall into the so-called semi-hard regime, where both fixed-order and high-energy dynamics come into play. Therefore, we propose a first version of a matching procedure aimed at combining NLO fixed-order computations, as obtained from POWHEG, with the NLL resummation of energy logarithms via JETHAD. According to our knowledge, this represents a novel implementation of a matching in the context of the high-energy resummation at NLL and for rapidity-separated two-particle final states.
