מפגש קבוצת התיאוריה של אנרגיות גבוהות: The quantization of folded strings in non-critical dimensions

Zoom: https://zoom.us/j/97785165783

​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.
