A classification of open string models

Article

Abstract

Open string models are classified using modular invariance. No good candidates for new models are found, though the existence of anE8 invariant model inR17, 1, a similar one inR5, 1 and of a supersymmetric model inR2, 1 cannot be excluded by this technique. An intriguing relation between the left moving and right moving sectors of the heterotic string emerges.
