On April 23 we will have a seminar by
Madalena Lemos (CERN)
Title: Surface defects in four-dimensional superconformal theories and chiral algebras
Abstract:
We study BPS surface defects in 4d superconformal field theories and show how symmetries constrain their anomaly coefficients. Focusing on N=(2,2) surface defects we review the protected subsector captured by a two-dimensional chiral algebra. We study the properties of the defect in this subsector and discuss how to compute the aforementioned anomaly coefficients.
