High-energy resummation in $$\Lambda _c$$ baryon production

Abstract

AbstractWe present a study on inclusive emissions of a double $$\Lambda _c$$ Λ c or of a $$\Lambda _c$$ Λ 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 t-channel resummation à la BFKL of energy logarithms up to the next-to-leading accuracy. We make use of the modular interface, suited to the analysis of different semi-hard reactions, employing the novel parameterization for the description of parton fragmentation into $$\Lambda _c$$ Λ 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.
