Graded Unitarity in the SCFT/VOA Correspondence
Arash Arabi Ardehali, Christopher Beem, Madalena Lemos +1
Vertex algebras that arise from four-dimensional, superconformal field theories inherit a collection of novel structural properties from their four-dimensional ance…
Regge trajectories for the (2,0) theories
Madalena Lemos, Balt C. van Rees, Xiang Zhao
We investigate the structure of conformal Regge trajectories for the maximally supersymmetric (2,0) theories in six dimensions. The different conformal multiplets in a single super…
Lectures on chiral algebras of superconformal field theories
Madalena Lemos
Any four-dimensional superconformal field theory possess a protected subsector isomorphic to a two-dimensional chiral algebra \cite{Beem:2013sza}. The goa…
Superconformal surfaces in four dimensions
Lorenzo Bianchi, Madalena Lemos
We study the constraints of superconformal symmetry on codimension two defects in four-dimensional superconformal field theories. We show that the one-point function of the stress…
Line defects and radiation in theories
Lorenzo Bianchi, Madalena Lemos, Marco Meineri
We study the conformal data of a generic superconformal half-BPS line defect in a four-dimensional theory. We prove a theory independent relation between the one-…
Universality at large transverse spin in defect CFT
Madalena Lemos, Pedro Liendo, Marco Meineri +1
We study the spectrum of local operators living on a defect in a generic conformal field theory, and their coupling to the local bulk operators. We establish the existence of unive…
Bootstrapping the Argyres-Douglas theory
Martina Cornagliotto, Madalena Lemos, Pedro Liendo
We apply bootstrap techniques in order to constrain the CFT data of the Argyres-Douglas theory, which is arguably the simplest of the Argyres-Douglas models. We study t…
Long Multiplet Bootstrap
Martina Cornagliotto, Madalena Lemos, Volker Schomerus
Applications of the bootstrap program to superconformal field theories promise unique new insights into their landscape and could even lead to the discovery of new models. Most exi…
Bootstrapping superconformal theories
Madalena Lemos, Pedro Liendo, Carlo Meneghelli +1
We initiate the bootstrap program for superconformal field theories (SCFTs) in four dimensions. The problem is considered from two fronts: the protected subsector d…
central charge bounds from chiral algebras
Madalena Lemos, Pedro Liendo
We study protected correlation functions in SCFT whose description is captured by a two-dimensional chiral algebra. Our analysis implies a new analytic bound for…
Bootstrapping chiral correlators
Madalena Lemos, Pedro Liendo
We apply the numerical bootstrap program to chiral operators in four-dimensional SCFTs. In the first part of this work we study four-point functions in which all f…
The superconformal bootstrap
Christopher Beem, Madalena Lemos, Leonardo Rastelli +1
We develop the conformal bootstrap program for six-dimensional conformal field theories with supersymmetry, focusing on the universal four-point function of stress tensor m…
The superconformal bootstrap
Christopher Beem, Madalena Lemos, Pedro Liendo +2
In this work we initiate the conformal bootstrap program for superconformal field theories in four dimensions. We promote an abstract operator-algebraic viewpoint…
Chiral Algebras for Trinion Theories
Madalena Lemos, Wolfger Peelaers
It was recently understood that one can identify a chiral algebra in any four-dimensional N=2 superconformal theory. In this note, we conjecture the full set of generators of the c…
Infinite Chiral Symmetry in Four Dimensions
Christopher Beem, Madalena Lemos, Pedro Liendo +3
We describe a new correspondence between four-dimensional conformal field theories with extended supersymmetry and two-dimensional chiral algebras. The meromorphic correlators of t…
The Superconformal Index of Class S Theories of Type D
Madalena Lemos, Wolfger Peelaers, Leonardo Rastelli
We consider the superconformal index of class S theories of type D, which arise by compactification of the (2,0) D_n theories on a punctured Riemann surface C. We also allow for th…
