Constraining the strength of $U(1{)}_A$ symmetry breaking using 2-flavour non-local NJL model

Abstract

In presence of magnetic field we have done a systematic analysis to constrain the strength of 't Hooft determinant term using LQCD data within a non-local version of two flavour NJL model. Topological susceptibility, being related to the axial symmetry, have also been calculated and compared with LQCD results to further validate our calculation.
