Polarization of inclusively produced $\Lambda_c$ in a QCD based hybrid model

TL;DR

This paper introduces a hybrid QCD-based model to predict the polarization of inclusively produced $ ext{Lambda}_c$ baryons, extending previous work on $ ext{Lambda}$ polarization to pion beams and $ ext{Lambda}_c$, with results aligning well with experimental data.

Contribution

The paper develops an extended hybrid model for $ ext{Lambda}_c$ polarization, incorporating pion beams and providing predictions consistent with recent experiments.

Findings

Model predicts $ ext{Lambda}_c$ polarization as a function of $x_F$ and $p_T$

Results show fair agreement with experimental measurements

Extends previous $ ext{Lambda}$ polarization models to $ ext{Lambda}_c$

Abstract

A hybrid model is presented for hadron polarization that is based on perturbative QCD subprocesses and the recombination of polarized quarks to form polarized hadrons. The model, originally applied to polarized $\Lambda$'s that were inclusively produced by proton beams, is extended to include pion beams and polarized $\Lambda_c$'s. The resulting polarizations are calculated as functions of $x_F$ and $p_T$ for high energies and are found to be in fair agreement with recent experiments.
