Axial anomaly in the gradient flow exact renormalization group (2201.08181v3)
Published 19 Jan 2022 in hep-th
Abstract: The gradient flow exact renormalization group (GFERG) is a formulation of the exact renormalization group that keeps exact gauge invariance. GFERG can keep also modified chiral invariance. We will show that this formulation reproduces the correct axial anomaly in four dimensions.
