Résumé |
I will discuss recent progress in understanding non-supersymmetric string theory
using anomalies. I will focus on two complementary aspects: anomalies in spacetime
and anomalies on the worldsheet. Spacetime anomalies provide constraints on
candidate theories and offer evidence that certain non-supersymmetric string
constructions are well-defined at the quantum level. Worldsheet anomalies, on the
other hand, encode restrictions on the two-dimensional theory describing string
propagation and, in turn, constrain the allowed target-space backgrounds. I will
explain how these worldsheet considerations can be used to identify and establish
the viability of certain non-supersymmetric backgrounds in type II string theory.
Based on [2310.06895] as well as upcoming work with L. Eberhardt and M. Tomasevic. |
