Description
Using the interacting instanton liquid model (IILM), we study an anomaly-driven breaking of chiral symmetry inspired by the Nambu-Jona-Lasinio (NJL) model with anomaly term, i.e., the KMT determinant term. In the NJL model, chiral symmetry dynamically breaks when there exists a sufficiently strong four-point quark interaction. Even though the four-point interaction is weaker than its critical value, chiral symmetry can be broken with a large anomaly contribution. This is anomaly-driven breaking of chiral symmetry. To apply that to the IILM, we generalize the definition of such symmetry breaking, and then investigate how they realize in the IILM. In this talk, we introduce the generalized definition for the anomaly-driven breaking. Also, I talk about the formulation of the IILM using in this work. Finally, I discuss simulation results for the quench and the unquench cases.
