Emergence of high-energy dynamics from cascade-baryon detections at the LHC

TL;DR

This paper introduces a new method for probing high-energy QCD dynamics at the LHC by detecting cascade baryons with jets, using advanced theoretical calculations to analyze their distributions.

Contribution

It proposes a novel inclusive detection channel involving cascade baryons and jets at the LHC, employing hybrid high-energy/collinear factorization with BFKL resummation.

Findings

Fragmentation mechanisms stabilize resummation effects.

Distributions show characteristic behaviors in rapidity, azimuthal angle, and transverse momentum.

Resummation effects are comparable to those observed in heavy-flavor production.

Abstract

We propose the inclusive detection at the LHC of a cascade $\Xi^-/\bar\Xi^+$ baryon in association with a jet, as a novel probe channel for the QCD dynamics at high energies. We investigate the behavior of a selection of distributions, differential in rapidity, azimuthal angle and/or transverse momenta, calculated via the hybrid high-energy/collinear factorization encoding the full next-to-leading BFKL resummation of energy logarithms. We come out with the conclusion that the fragmentation mechanism underlying the production of $\Xi^-/\bar\Xi^+$ baryon states leads to stabilization effects of the resummation, similar to those recently observed in the context of heavy-flavor studies within the same formalism.
