Hybrid high-energy/collinear factorization in a heavy-light dijets system reaction

Abstract

We propose the inclusive hadroproduction of a heavy-light dijet system, as a new channel for the investigation of high-energy QCD. We build up a hybrid factorization that incorporates a partial next-to-leading BFKL resummation inside the standard collinear description of observables. We present a detailed analysis of different distributions: cross-section summed over azimuthal angles and differential in rapidity and azimuthal distribution. The stability that these distributions show under higher-order corrections motivates our interest in future studies, doable at new generation colliding machines.
