Diffractive production of $\Lambda$ hyperons in the high-energy limit of strong interactions

TL;DR

This paper explores the production of $ ext{Lambda}$ hyperons in high-energy collisions to test QCD energy logarithm resummation, providing predictions for experiments like CMS and CASTOR.

Contribution

It introduces a novel approach to study $ ext{Lambda}$ hyperon production as a probe for QCD resummation effects in semi-hard processes.

Findings

Predictions for cross sections and azimuthal correlations in $ ext{Lambda}$ production.

Analysis shows $ ext{Lambda}$ tagging facilitates comparison between theory and experiment.

Highlights the relevance of $ ext{Lambda}$ hyperons in probing QCD dynamics.

Abstract

We propose the study of the inclusive production of two $\Lambda$ hyperons or a single $\Lambda$-particle in association with a jet, featuring high transverse momenta and large separation in rapidity, as a probe channel of the resummation of energy logarithms in the QCD perturbative series. We give predictions, shaped on kinematic ranges typical of CMS and of the backward CASTOR detector, for cross section and azimuthal-correlation moments between the two emitted objects, showing how considering the tag of $\Lambda$ baryons eases the comparison between theoretical results and experimental data in the phenomenological context of semi-hard reactions.
