Maths HEP Lunchtime Seminars: Mass renormalization in (super)string theory
12 December 2014 13:00 in CM221
The conventional way of computing string theory amplitudes is not sufficient to compute mass renormalization of massive states in string theory. The aim of this talk is to define a suitable off-shell continuation of Polyakov approach. Then this off-shell continuation will be used to compute mass-renormalization. At the end we will generalise this method to superstring theory.
