Abstract
Relatively low crossover temperature suggests that chiral
symmetry restoration in Quantum Chromodynamics
may well be described within the low-energy
effective theory. The shape of the pseudocritical line in the T-μ
plane is estimated within this assumption. No critical endpoint is found
for physical values of quark masses.
