What is the status of the research on the critical point (the multicritical point which connects the 2nd order phase transition and the 1st order phase transitions or the crossover) of QCD phase diagram?

The "Thermal" Critical Point is mentioned and summarized in this paper: http://physics.aps.org/articles/v2/5

Have the critical point(s) in QCD phase diagram been verified? Other than the "thermal Critical Point," are there also the non-thermal low or zero temperature critical point, say, the "Quantum" critical point in QCD phase diagram?

What are the status and consensus in the theory community as well as the experiment community?
