Higgsless Lagrangian SCFTs and Strongly Finite VOAs
Siqi Chen, Anirudh Deb, Leonardo Rastelli
Vertex operator algebras (VOAs) are well studied in both mathematics and physics. The best understood class is that of strongly rational VOAs, whose representation category is maxi…
Bootstrapping Pion Form Factors at Large
Jan Albert, Dilara Kosva, Leonardo Rastelli
We initiate a bootstrap study of pion form factors in large QCD. We consider the mixed system of the vector-current two-point function, the pion vector form factor, and the pio…
Where is tree-level heterotic string theory?
Mathieu Boisvert, Waltraut Knop, Leonardo Rastelli
We continue the tree-level S-matrix bootstrap program for quantum gravity, now in ten-dimensional theories with half-maximal supersymmetry. This setting includes the heterotic stri…
Moduli Spaces in CFT: Large Charge Operators
Gabriel Cuomo, Leonardo Rastelli, Adar Sharon
Using the large-charge expansion, we prove a necessary condition for a CFT to exhibit conformal symmetry breaking, under the assumption that a continuous global symmetry is ${\it a…
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…
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…
