The potential critical endpoint of the QCD (T,\\mu)-phase diagram is widely expected to be part of this surface. Since for \\mu=0 with physical quark masses QCD is known to exhibit an analytic crossover, this expectation requires the region of chiral transitions to expand with \\mu for a chiral critical endpoint to exist.
