Résumé |
Many superconformal field theories (SCFTs) in four dimensions arise from
compactifying parent six-dimensional theories on Riemann surfaces. A famous
example is the class S family. A vast generalization has long been expected from
N=(1,0)-supersymmetric parents, but the role of punctures has remained poorly
understood. Using a systematic study of holographic defects in the probe
approximation, I will obtain a classification of BPS punctures for these models.
This framework reproduces the known class S results in a suitable limit, and
predicts new N=1 four-dimensional SCFTs together with their large-N conformal
anomalies. |
