Hidden Modulus in the Extended Veneziano-Yankielowicz Theory

TL;DR

This paper investigates the structure of domain walls in the extended Veneziano-Yankielowicz theory, revealing a noncompact modulus and a family of degenerate solutions due to a valley of vacua, but these do not align with N=1 super Yang-Mills expectations.

Contribution

It uncovers a noncompact modulus and substructure in domain walls within the extended Veneziano-Yankielowicz theory, highlighting differences from N=1 super Yang-Mills.

Findings

Discovery of a noncompact modulus in the theory

Identification of a valley of vacua leading to degenerate solutions

Mismatch with expected properties of N=1 super Yang-Mills domain walls

Abstract

The issue of domain walls in the recently extended Veneziano-Yankielowicz theory is investigated and we show that they have an interesting substructure. We also demonstrate the presence of a noncompact modulus. The associated family of degenerate solutions is physically due to the presence of a valley of vacua in the enlarged space of fields. This is a feature of the extended Veneziano-Yankielowicz theory. Unfortunately the above properties do not match the ones expected for the domain walls of N=1 super Yang-Mills.
