# New N=2 superconformal field theories from S-folds

@article{Giacomelli2020NewNS, title={New N=2 superconformal field theories from S-folds}, author={Simone Giacomelli and C. Meneghelli and Wolfger Peelaers}, journal={arXiv: High Energy Physics - Theory}, year={2020} }

We study the four-dimensional N=2 superconformal field theories that describe D3-branes probing the recently constructed N=2 S-folds in F-theory. We introduce a novel, infinite class of superconformal field theories related to S-fold theories via partial Higgsing. We determine several properties of both the S-fold models and this new class of theories, including their central charges, Coulomb branch spectrum, and moduli spaces of vacua, by bringing to bear an array of field-theoretical… Expand
