Abstract
We propose the study of the inclusive hadroproduction of a heavy-flavored jet in association with a light jet, as a probe channel of strong interactions at high energies. We build up a hybrid factorization that encodes genuine high-energy effects, provided by a partial next-to-leading BFKL resummation, inside the standard collinear structure of the cross section. We present a detailed analysis of different distributions, shaped on kinematic ranges typical of experimental analyses at the Large Hadron Collider, and differential in rapidity, azimuthal angle and transverse momentum. The fair stability that these distributions exhibit under higher-order corrections motivates our interest toward future studies. Here, the hybrid factorization could help to deepen our understanding of heavy-flavor physics in wider kinematic ranges, like the ones accessible at the Electron-Ion Collider.

Summary
Heavy-flavored emissions in hadronic and leptohadronic collisions are commonly recognized as excellent probe channels of the dynamics of strong interactions. It stems from the fact that higher-order (NLA) corrections are large, both in the kernel of the Green’s function and in the nonuniversal impact factors, and with opposite sign with respect to LLA terms This translates in a raised sensitivity of the series on renormalization scale variation, which, in Mueller–Navelet case, is so strong to prevent any attempt to perform reliable analyses around “natural” scales (which correspond, for light jets, to their pT). Encouraging clues that a fair stability under higher-order BFKL corrections has been reached came out just recently [102] in the context of the inclusive Higgs-plus-jet production and are expected in the inclusive Drell–Yan-plus-jet process [100] In those cases, the large energy scales that act as stabilizers of rapidity and pT-distributions mostly come from the transverse mass of the emitted boson, while a similar outcome cannot be obtained in the case of light-object emissions.
