Title The quantization of folded strings in non-critical dimensions
Abstract I will talk about some problems that arise when attempting to quantize rotating strings semiclassically, in the critical and non-critical dimensions. The problems are divergences associated with folding points in the string. A rotating closed string is a basic system that suffers from this problem, and I show how we deal with it by treating the fold as a boundary and placing mass terms there. The mass terms are also motivated by phenomenology and holographic models of QCD (such as the Sakai-Sugimoto model). Based on an upcoming paper by J. Sonnenschein a
