New Exotic Operators in the Spectrum of Wilson Lines in General Representations
Daniele Artico, Carlo Meneghelli, Michele Savi +1
Wilson lines are fundamental probes of gauge theories. We show that, in sufficiently rich representations, they support a large new class of operator insertions. For half-BPS lines…
A universal W-algebra for N=4 super Yang-Mills
Federico Bonetti, Carlo Meneghelli
Using bootstrap methods, we provide evidence for the existence of a non-linear W-algebra, denoted , which contains the small N= 4 super Virasoro algebra and fe…
The Nilpotency Index for 4d SCFTs
Anirudh Deb, Carlo Meneghelli, Leonardo Rastelli
A well-developed classification program for 4d super conformal field theories (SCFTs) leverages Seiberg-Witten geometry on the Coulomb branch of vacua; theories are…
Free field realizations for rank-one SCFTs
Christopher Beem, Anirudh Deb, Mario Martone +2
In this paper, we construct the associated vertex operator algebras for all superconformal field theories of rank one. We give a uniform presentation through free-f…
Unmixing the Wilson line defect CFT. Part II: analytic bootstrap
Pietro Ferrero, Carlo Meneghelli
In this second installment of a series of two papers on the -BPS Wilson line defect CFT in super Yang-Mills, we focus on dynamical aspects of the theo…
Unmixing the Wilson line defect CFT. Part I: spectrum and kinematics
Pietro Ferrero, Carlo Meneghelli
This is the first of a series of two papers in which we study the one-dimensional defect CFT defined by insertions of local operators along a -BPS Wilson line in $\ma…
