Chiral phase transition and baryon number conservation
In the standard R4 embedding of the chiral O(4) model in 3+1 dimensions the winding number is not conserved near the chiral phase transition and thus no longer can be identified with baryon number. In order to reestablish conserved baryon number in effective low-energy models near and above the critical temperature Tc it is argued that insisting in O(N) models on the angular nature of the chira...
متن کاملDetecting a First-Order Transition in the QCD Phase Diagram with Baryon-Baryon Correlations
We suggest baryon-baryon correlations as an experimentally accessible signature for a first-order phase transition between a baryon-rich phase, like quarkyonic, and a baryon-suppressed hadronic phase in the QCD phase diagram.
متن کاملOn the QCD Phase Transition at Finite Baryon Density
We investigate the QCD chiral phase transition at finite chemical potential μ, using the renormalization group (RG) to characterize the infrared behavior of sigma models constrained by the flavor and spacetime symmetries. The results are similar to those obtained from RG analysis of the finite temperature transition at zero baryon density. When there are more than two massless flavors of quarks...
متن کاملChiral Phase Transition in QCD
We employ non–perturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass dependence of quantities like the chiral condensate or the pion mass. Our treatment covers both the chiral perturbation theory domain of validity and the domain of validity of universality associated with critical phenome...
متن کاملChiral Transition and Baryon-number Susceptibility
b We discuss the baryon-number susceptibility χ B and related topics which include the density fluctuations around the critical point of the chiral transition at finite temperature T and baryon density ρ B. Phenomenological implications of the density fluctuations near the first-order chiral transition at finite density are also discussed.
