Baryon modes in string breaking from gauge/string duality

TL;DR

This paper investigates string breaking in effective models mimicking QCD, focusing on baryon modes and estimating breaking distances at various chemical potentials, suggesting enhanced baryon production in dense matter.

Contribution

It provides new estimates of string breaking distances and links baryon production enhancements to chemical potential effects in dense baryonic environments.

Findings

String breaking distances are estimated at zero and non-zero chemical potentials.

Baryon production is enhanced in dense baryonic matter.

Enhanced $ ext{Λ}_c^+$ production in PbPb collisions is attributed to higher chemical potentials.

Abstract

We consider the string breaking phenomenon within effective string models which purport to mimic QCD with two light flavors, with a special attention to baryon modes. We make some estimates of the string breaking distances at zero and non-zero baryon chemical potentials. Our estimates point towards the enhancement of baryon production in strong decays of heavy mesons in dense baryonic matter. We also suggest that the enhanced production of $\Lambda_c^+$ baryons in PbPb collisions is mainly due to larger values of chemical potential.
