Nuclear matter to strange matter transition in holographic QCD

TL;DR

This paper develops a holographic QCD model to analyze the transition from nuclear to strange matter, revealing a density-dependent transition and the equal population of quark flavors at high densities, with Pauli principle effects modeled via D-brane dynamics.

Contribution

It introduces a holographic QCD framework incorporating force balance and energy minimization to study matter transitions and flavor population dynamics.

Findings

Identifies a well-defined transition density as a function of quark mass.

Shows equal quark flavor population at very high densities.

Models Pauli principle effects through D-brane interactions.

Abstract

We construct a simple holographic QCD model to study nuclear matter to strange matter transition. The interaction of dense medium and hadrons is taken care of by imposing the force balancing condition for stable D4/D6/D6 configuration. By considering the intermediate and light flavor branes interacting with baryon vertex homogeneously distributed along R^3 space and requesting the energy minimization, we find that there is a well defined transition density as a function of current quark mass. We also find that as density goes up very high, intermediate (or heavy) and light quarks populate equally as expected from the Pauli principle. In this sense, the effect of the Pauli principle is realized as dynamics of D-branes.
