Abstract

A bstract Six-dimensional superconformal field theories (SCFTs) give rise to four-dimensional (4d) ones when compactified on Riemann surfaces. In the N= (2, 0) N = 2 0 case, this yields the famous class S family. For N= (1, 0) N = 1 0 theories that arise from linear unitary quivers, the holographic duals of the 4d theories are known in massive IIA supergravity, but only without punctures. Working in the probe approximation, we identify all possible BPS punctures in these models and characterize them by computing their defect Weyl anomalies. For class S, our results reproduce the known expressions in the appropriate limit. In the more general N= (1, 0) N = 1 0 case, they predict new 4d SCFTs and their large- N anomaly coefficients.
