Abstract

An increase in the size of coherent domains in the one component (Formula presented) field theory under the influence of a uniformly changing external magnetic field near the critical end point (Formula presented) was proposed recently as an estimate also for the variation of the chiral correlation length of QCD near its respective hypothetical end point in the (Formula presented) plane. The present detailed numerical investigation of the effective model suggests that passing by the critical QCD end point with a realistic rate of temperature change will trigger large amplitude oscillations in the temporal variation of the chiral correlation length. A simple mechanism for producing this phenomenon is suggested.
