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…
