On the construction of gauge theories from non critical type 0 strings

TL;DR

This paper explores how non critical type 0 string theories can be used to construct gauge theories, demonstrating properties like entropy matching, area law, and mass gap, which are relevant for understanding non-perturbative aspects of Yang-Mills theories.

Contribution

It provides a novel approach to constructing gauge theories from non critical string theories, including finite temperature effects and the emergence of key non-perturbative features.

Findings

Entropy matches that of weakly interacting Yang-Mills bosons.

The theory exhibits an area law and a mass gap.

These features persist for p>4.

Abstract

We investigate Polyakov's proposal of constructing Yang-Mills theories by using non critical type 0 strings. We break conformal invariance by putting the system at finite temperature and find that the entropy of the cosmological solutions for these theories matches that of a gas of weakly interacting Yang-Mills bosons, up to a numerical constant. The computation of the entropy using the effective action approach presents some novelties in that the whole contribution comes from the RR fields. We also find an area law and a mass gap in the theory and show that such behavior persists for $p>4$. We comment on the possible physical meaning of this result.
