Se p 20 05 Critical end point and its consequences
Recently a lot of evidence that there exists a critical end point (CEP) in the QCD phase diagram has been accumulating. However, so far, no reliable equation of state with the CEP has been employed in hydrodynamical calculations. In this article, we construct the equations of state with the CEP on the basis of the universality hypothesis and show that the CEP acts as an attractor of isentropic ...
متن کاملThe critical end point of quantum chromodynamics
We investigate the critical end point (CEP) of QCD with two flavours of light dynamical quarks at finite lattice cutoff a = 1/4T using a Taylor expansion of the baryon number susceptibility. We find a strong volume dependence of the position of the critical end point. In the large volume limit we obtain T /Tc ≈ 0.95 and μE B /T E ≈ 1.1, where Tc is the cross over temperature at zero chemical po...
متن کاملFinding the critical end point of QCD: lattice and experiment
The current status of the search for the critical end point on the lattice and in experiments is discussed. A naive extrapolation is given of lattice results on the location of the critical end point to the continuum limit with the correct pion mass. An interpretation of current results on fluctuations is provided. A new method of analysis of experimental data is discussed, which provides a che...
متن کامل3He Vapor Pressure near Its Critical Point
Between 0.65 K and 3.2 K, the temperature dependence of the vapor pressure P of 3He is defined by the International Temperature Scale of 1990 (ITS-90). However, the ITS-90 vapor pressure equation was not designed to be consistent with the scaling law required for the second temperature derivative of the vapor pressure in the vicinity of the liquid-vapor critical point. In this paper, two scalin...
متن کاملDynamic nature at the QCD Critical End Point
We discuss the dynamic nature of the critical end point (CEP) which is the end point of the first order chiral phase transition. In the earlier work, Son and Stephanov analyzed the Langevin equation for CEP taking care of the mixing effect between the chiral condensate and the baryon number density and showed that the dynamic universality class of CEP is the model H, the same as that of the end...
