CMSA Quantum Matter in Mathematics and Physics: Construction of Lattice Chiral Gauge Theory
Herbert Neuberger - Rutgers University
The continuum formal path integral over Euclidean fermions in the background of a Euclidean gauge field is replaced by the quantum mechanics of an auxiliary system of non-self-interacting fermions. No-go "theorems" are avoided.
The main features of chiral fermions arrived at by formal continuum arguments are preserved on the lattice.
