Dressing and Screening in Anti-de Sitter
Ankur, Lorenzo Di Pietro, Victor Gorbenko +2
Motivated by a question of defining gauge-invariant observables in cosmology and by the close connection between perturbation theory in de Sitter (dS) and Anti-de Sitter (AdS), we…
F-theorem for Quantum Field Theories in Anti-de Sitter Space
Davide Bason, Christian Copetti, Lorenzo Di Pietro +2
We introduce a regularized free energy for massive quantum field theories (QFTs) on Anti-de Sitter space (AdS). We conjecture this quantity to be monoton…
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…
BCFT One-point Functions of Coulomb Branch Operators
Davide Bason, Lorenzo Di Pietro, Roberto Valandro +1
We show that supersymmetry can be used to compute the BCFT one-point function coefficients for chiral primary operators, in 4d SCFTs with -BPS boundary…
Super Yang-Mills in AdS and -maximization
Davide Bason, Christian Copetti, Lorenzo Di Pietro +1
We investigate the dynamics of four-dimensional super Yang--Mills theory on an AdS background. We propose that the boundary conditions that preserve the AdS…
Cosmological Correlators at Finite Coupling
Lorenzo Di Pietro, Victor Gorbenko, Shota Komatsu
We study finite-coupling effects of QFT on a rigid de Sitter (dS) background taking the vector model at large as a solvable example. Extending standard large techniq…
