Conformal QED in AdS as a BCFT
Fabiana De Cesare, Simone Giombi
We study conformal Quantum Electrodynamics (QED) coupled to either massless fermions or conformally coupled scalars in Euclidean Anti-de Sitter (AdS) space for $d <…
QFT as a set of ODEs: higher dimensions
Fabiana De Cesare, Manuel Loparco
Correlation functions of local operators in Quantum Field Theory (QFT) in Anti-de Sitter space (AdS) are completely fixed by the QFT data: the set of scaling dimensions and O…
Disturbing news about the expansion II. Assessing the recombination scenario
Fabiana De Cesare, Slava Rychkov
In [De Cesare, Rychkov (2025)], we revisited the expansion in the Non-Linear Sigma Model (NLSM), emphasizing the existence of a protected operator which is a closed…
QCD in AdS
Riccardo Ciccone, Fabiana De Cesare, Lorenzo Di Pietro +1
We study QCD on AdS space with scalars or fermions in the fundamental representation, extending earlier results on pure Yang-Mills theory. In the latter, the Dirichlet boundary con…
Disturbing news about the expansion
Fabiana De Cesare, Slava Rychkov
The Non-Linear Sigma Model (NLSM) in has long been conjectured to describe the same conformal field theory (CFT) as the Wilson-Fisher (WF) fixed point obtain…
