High-energy resummation in $\Lambda_c$ baryon production

High Energy Physics - Phenomenology 2021-09-15 v2

Abstract

We present a study on inclusive emissions of a double Λc\Lambda_c or of a Λc\Lambda_c plus a light-flavored jet system as probe channels in the semi-hard regime of QCD. Our formalism relies on the so-called hybrid high-energy/collinear factorization, where the standard collinear description is supplemented by the tt-channel resummation \`a la BFKL of energy logarithms up to the next-to-leading accuracy. We make use of the JETHAD modular interface, suited to the analysis of different semi-hard reactions, employing the novel KKSS19 parameterization for the description of parton fragmentation into Λc\Lambda_c baryons. We provide predictions for rapidity distributions and azimuthal correlations, that can be studied at current and forthcoming LHC configurations, hunting for possible stabilizing effects of the high-energy series.
