# Flavor dependence of baryon melting temperature in effective models of QCD

@article{TorresRincon2015FlavorDO, title={Flavor dependence of baryon melting temperature in effective models of QCD}, author={Juan M. Torres-Rincon and Benjamin Sintes and Joerg Aichelin}, journal={Physical Review C}, year={2015}, volume={91}, pages={065206} }

We apply the three-flavor (Polyakov-)Nambu-Jona-Lasinio model to generate baryons as quark-diquark bound states using many-body techniques at finite temperature. All the baryonic states belonging to the octet and decuplet flavor representations are generated in the isospin-symmetric case. For each state we extract the melting temperature at which the baryon may decay into a quark-diquark pair. We seek for an evidence of the strangeness dependence of the baryon melting temperature as suggested…
