Bayesian inference of the Quantum Chromodynamics Strange Equation of State from holography

ORAL

Abstract

Quantum Chromodynamics (QCD) is the fundamental theory of the strong interaction. However, QCD cannot be calculated beyond zero baryon chemical potential (mu_B = 0) meaning that we do not know features of the equation of state (EoS) phase diagram at finite mu_B. The model we are using relates a theory of gravity in 5 dimensions to a quantum field theory in 4 dimensions. Bayesian inference is used to obtain the optimal parameters for the model in order to be within the bounds of the EoS lattice results. This analysis can also be performed with the lattice eos results for strangeness, allowing us to explore the phase diagram in the plane of T-mu_S and its related features.
