Seminar April 23: M. Lemos

On April 23 we will have a seminar by

Madalena Lemos (CERN)

Title: Surface defects in four-dimensional superconformal theories and chiral algebras

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.
