Non-perturbative renormalization for lattice massive QED${}_2$: the ultraviolet problem

Simone Fabbri, Vieri Mastropietro, Bruno Renzi

We consider a lattice regularization, preserving Ward Identities (WI) and with a Wilson term, of the Massive QED${}_2$, describing a fermion with mass $m$ and charge $\mathsf{e}$ int…
