Mapping the QCD Phase Diagram
The QCD vacuum in which we live, which has the familiar hadrons as its excitations, is but one phase of QCD, and far from the simplest one at that. One way to better understand this phase and the nonperturbative dynamics of QCD more generally is to study other phases and the transitions between phases. We are engaged in a voyage of exploration, mapping the QCD phase diagram as a function of tem...
متن کاملTowards the QCD phase diagram
We summarize our recent results on the phase diagram of QCD with N f = 2+1 quark flavors, as a function of temperature T and quark chemical potential μ . Using staggered fermions, lattices with temporal extent Nt = 4, and the exact RHMC algorithm, we first determine the critical line in the quark mass plane (mu,d ,ms) where the finite temperature transition at μ = 0 is second order. We confirm ...
متن کاملThe Phase Diagram of QCD
I use simple thermodynamic reasoning to argue that at temperatures of order a trillion kelvin, QCD, the theory which describes strongly interacting particles such as protons and neutrons under normal conditions, undergoes a phase transition to a plasma of more elementary constituents called quarks and gluons. I review what is known about the plasma phase both from theoretical calculations and f...
متن کاملQCD phase diagram: an overview
The aim of this review is to summarize the contemporary understanding of the QCD phase diagram as a function of temperature T and baryo-chemical potential µ B. The focus is on recent theoretical developments due to lattice simulations of the phase diagram.
متن کاملThe QCD Phase Diagram from Chiral Approaches
I show an updated QCD phase diagram with recent developments from chiral effective theories and phenomenological models. Expected signals of a QCD critical point accessible in heavy-ion collisions are also discussed. In particular, non-monotonic behavior of fluctuations associated with conserved charges is focused on.
