QCD Phase Diagram with a Critical Point from Holography
Abstract
We use a holographic black hole approach to study the QCD phase diagram at finite temperature and baryon-chemical potential, $\\mu_B$. \nThe free parameters of our black hole model were engineered to mimic the equation of state of QCD obtained on the lattice at zero $\\mu_B$. Once the parameters were fixed, the black hole model predicts the equation of state at finite $\\mu_B$. \nIn this contribution, we discuss the mapping of the black hole model in the QCD phase diagram and show that the crossover transition, between hadrons and the quark-gluon plasma, ends in a critical point where a first order line begins.
