N=1 String Duality

TL;DR

This paper explores dualities among different string theories and supergravity in four dimensions with N=1 supersymmetry, revealing theories with trivial IR limits and those flowing to N=4 fixed points.

Contribution

It identifies dualities connecting Type IIA, eleven-dimensional supergravity, and heterotic string theories with novel IR behaviors in four dimensions.

Findings

Discovery of theories with trivial IR limits at enhanced symmetry points

Identification of theories with N=1 supersymmetry flowing to N=4 fixed line

Establishment of dualities among multiple string theories and supergravity

Abstract

We discuss duality between Type IIA string theory, eleven-dimensional supergravity, and heterotic string theory in four spacetime dimensions with $N=1$ supersymmetry. We find theories whose infrared limit is trivial at enhanced symmetry points as well as theories with $N=1$ supersymmetry but the field content of $N=4$ theories which flow to the $N=4$ fixed line in the infrared.
