Schwinger Model In Noncommutating Space-Time

TL;DR

This paper explores the Schwinger model in a noncommutative space-time, revealing a novel background interaction while maintaining unitarity and causality in the theory.

Contribution

It introduces a noncommutative framework for the Schwinger model, highlighting the emergence of a background interaction as a new feature.

Findings

The model exhibits a massive boson interacting with a background.

Unitarity and causality are preserved in the noncommutative setting.

The background interaction is a novel feature due to noncommutativity.

Abstract

The 1+1 dimensional bosonised Schwinger model has been studied in a noncommutative scenario. The theory in the reduced phase space exhibits a massive boson interacting with a background. The emergence of this background interaction is a novel feature due to noncommutativity. The structure of the theory ensures unitarity and causality.
