Soldering Chiralities II: Non-Abelian Case

TL;DR

This paper explores the extension of the soldering process to non-abelian chiral WZW models, resulting in a non-chiral WZW model on a curved 2D spacetime, advancing understanding of non-abelian conformal field theories.

Contribution

It introduces a non-abelian soldering method for chiral WZW models, producing a non-chiral model on curved spacetime, which is a novel development in the field.

Findings

Successful extension of soldering to non-abelian models

Construction of a non-chiral WZW model on curved spacetime

Insights into non-abelian conformal field theories

Abstract

We study the non-abelian extension of the soldering process of two chiral WZW models of opposite chiralities, resulting in a (non-chiral) WZW model living in a 2D space-time with non trivial Riemanian curvature.
