Title: Towards a Non-Supersymmetric String Phenomenology

Abstract: We explore the properties of string models with spontaneous supersymmetry breaking introduced via Scherk-Schwarz compactification. Such models have a non-supersymmetric spectrum and a cosmological constant that vanishes in the decompactification limit, but we provide additional insight into their interpolation from non-tachyonic non-supersymmetric models in the small radius limit. We show that there exist  "quasi-stable" models that have exponentially suppressed cosmological constant which are phenomenologically viable. The general phenomenological properties and myriad possibilities of these models are discussed.
