Holographic Duals of Argyres-Douglas Theories
Abstract
We present new AdS5 solutions in 11d supergravity and identify them as the gravity duals of a class of 4d N = 2 SCFTs of Argyres-Douglas type, engineered by a stack of M5-branes wrapped on a sphere with one irregular puncture and one regular puncture. The gravity solutions feature an internal M5-brane source, which is dual to the irregular puncture. Thanks to a novel St\"uckelberg mechanism involving an axion originating from the expansion of the M-theory 3-form, one of the isometry generators on the gravity side is not mapped to a continuous symmetry on the SCFT side.
