A Massive Non-Abelian Vector Model

TL;DR

This paper explores a massive non-Abelian vector model where a Lagrange multiplier enforces classical equations, limiting radiative corrections to one loop and analyzing the resulting theoretical implications.

Contribution

It introduces a Lagrange multiplier approach to restrict radiative corrections in a massive non-Abelian vector model, a novel method in the field.

Findings

Radiative corrections are limited to one loop due to the Lagrange multiplier.

The model's classical equations are enforced at the quantum level.

Implications for the consistency and quantization of massive non-Abelian vectors.

Abstract

The introduction of a Lagrange multiplier field to ensure that the classical equations of motion are satisfied serves to restrict radiative corrections in a model to being only one loop. The consequences of this for a massive non-Abelian vector model are considered.
