Comments on Baryon Melting in Quark Gluon Plasma with Gluon Condensation

TL;DR

This paper investigates baryon melting in a strongly coupled quark-gluon plasma with gluon condensation, revealing that baryons melt at lower temperatures than previously thought, using a holographic model with a dilaton black hole.

Contribution

It introduces a new holographic model with a dilaton black hole to study baryon melting in gluon-condensed plasma, showing lower melting temperatures than earlier estimates.

Findings

Baryons melt at lower temperatures in the presence of gluon condensation.

The holographic model captures the effects of gluon condensation on baryon stability.

Baryon screening and phase transitions are affected by the dilaton field.

Abstract

We consider a black hole solution with a non-trivial dilaton from IIB super gravity which is expected to describe a strongly coupled hot gauge plasma with non-vanishing gluon condensation present. We construct a rotating and moving baryon to probe the screening and phases of the plasma. Melting of the baryons in hot plasma in this background had been studied previously, however, we show that baryons melt much lower temperature than has been suggested previously.
