On the Generalised Pauli--Villars Regularization of the Standard Model

TL;DR

This paper discusses a nonlocal formulation of the Standard Model achieved through a generalized Pauli--Villars regularization, simplifying the Lagrangian while maintaining regularization properties.

Contribution

It introduces a new nonlocal regularization approach for the Standard Model based on a simplified Lagrangian, extending previous methods.

Findings

The regularization leads to a nonlocal but consistent theory.

The Lagrangian of the regularized model is notably simpler.

The approach preserves key features of the Standard Model.

Abstract

We show that the regularization of the Standard Model proposed by Frolov and Slavnov describes a nonlocal theory with quite simple Lagrangian.
