Description

We compute the vacuum energy density as a function of the quark condensate in the interacting instanton liquid model (IILM) and examine a pattern of dynamical chiral symmetry breaking from the behavior of the vacuum energy density at the origin. This evaluation is performed by using a numerical simulation of the IILM. We find that chiral symmetry is broken in the U(1)_A anomaly assisted way in the IILM with three-flavor dynamical quarks. We also find the instanton-quark interaction included in the IILM plays a crucial role for the symmetry breaking by comparing the full and the quenched IILM calculations.
