Fragmentation Functions:Modifications and new Applications

TL;DR

This paper introduces a modified heavy quark fragmentation model that incorporates Regge trajectory peculiarities, resulting in improved agreement with experimental data for meson and baryon production.

Contribution

It proposes a novel modification to the standard quark fragmentation model accounting for heavy quark Regge trajectories, enhancing predictive accuracy.

Findings

Better fit to experimental meson and baryon production data

Incorporates Regge trajectory effects for heavy quarks

Improves upon standard fragmentation models

Abstract

We present a heavy quark fragmentation mechanism based on a modified version of the standard model of quark fragmentation, taking into account peculiarities of the Regge trajectories of quarkonia containing heavy quarks. The modified model describes the experimental data more satisfactorily both for meson and baryon production.
