Baryon modes in string breaking from gauge/string duality

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.
