Abstract

We propose the inclusive detection at the LHC of a cascade ${\mathrm{\Xi }}^{-}/{\overline{\mathrm{\Xi }}}^{+}$ 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 ${\mathrm{\Xi }}^{-}/{\overline{\mathrm{\Xi }}}^{+}$ 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.
