Description
The Standard model as a chiral gauge theory is the core foundation of particle physics. Yet, no consensus has been reached on non-perturbative formulations of chiral gauge theories although a few number of promising theoretical models have been constructed. In this work, we exam the extra dimension or domain wall fermion approach. Firstly, we numerically tested the slab (Grabowska-Kaplan) proposal in 2+1 dimensional lattice with a background gauge field and showed anomaly inflow, anomaly cancellation, and the behaviour of the boundary chiral model under different flow of the gauge field. Secondly, we tested a recently proposed proposal with a disk shape defect with a $ S_1 × T_1 $ boundary under annealing flow of the background gauge field. Similarly, we demonstrate the mechanism of anomaly inflow and anomaly cancellation. This work is in collaboration of Rohith Karur and Srimoyee Sen.
