We describe a new correspondence between four-dimensional conformal field theories with
extended supersymmetry and two-dimensional chiral algebras. The meromorphic …

Starting with a gentle approach to the Alday–Gaiotto–Tachikawa (AGT) correspondence
from its 6d origin, these notes provide a wide (albeit shallow) survey of the literature on …

We study the N= 2 four-dimensional superconformal index in various interesting limits, such
that only states annihilated by more than one supercharge contribute. Extrapolating from the …

We study the local properties of a class of codimension-2 defects of the 6d theories of type
J= A, D, E labeled by nilpotent orbits of a Lie algebra, where is determined by J and the …

We describe a procedure for classifying\(\mathcal {N}= 2\) superconformal theories of the
type introduced by Davide Gaiotto. Any curve, C, on which the 6D AN− 1 SCFT is …

We conjecture a closed-form expression for the Schur limit of the superconformal index of
two infinite series of Argyres–Douglas (AD) superconformal field theories (SCFTs): the $({A} …

A bstract Four-dimensional\(\mathcal {N}\)= 2 superconformal field theories have families of
protected correlation functions that possess the structure of two-dimensional chiral algebras …

A bstract It is widely considered that the classical Higgs branch of 4d\(\mathcal {N}\)= 2
SQCD is a well understood object. However there is no satisfactory understanding of its …
