DESCRIPTION:Speakers: 金龙 党 (北京大学)\nThe Standard model as a c
 hiral gauge theory is the core foundation of particle physics. Yet\, no co
 nsensus has been reached on non-perturbative formulations of chiral gauge 
 theories although a few number of promising theoretical models have been c
 onstructed. In this work\, we exam the extra dimension or domain wall ferm
 ion approach. Firstly\, we numerically tested the slab (Grabowska-Kaplan) 
 proposal in 2+1 dimensional lattice with a background gauge field and show
 ed anomaly inflow\, anomaly cancellation\, and the behaviour of the bounda
 ry chiral model under different flow of the gauge field. Secondly\, we tes
 ted a recently proposed proposal with a disk shape defect with a  boundary
  under annealing flow of the background gauge field. Similarly\, we demons
 trate the mechanism of anomaly inflow and anomaly cancellation.\n\nhttps:/
