Bounds on scattering amplitudes of non-identical scalar particles in 4d
Gabriele Ferretti, Denis Karateev, Alessandro Piazza +1
We initiate the study of two-to-two scattering amplitudes involving two distinct scalar particles in spacetime dimensions using the primal S-matrix bootstrap. We impose a $…
A Bootstrap Study of Confinement in AdS
Lorenzo Di Pietro, Stefanos R. Kousvos, Marco Meineri +3
Yang-Mills theory in AdS with Dirichlet boundary conditions is expected to undergo a transition as the AdS radius varies, since the boundary data is incompatible with confine…
Bootstrapping the Simplest Deconfined Quantum Critical Point
Shai M. Chester, Alessandro Piazza, Marten Reehorst +1
We study the case of the model, which is a field theory of complex scalars in coupled to an Abelian gauge field with global symmetry.…
On the expansion in CFTs with degenerate operators
Agnese Bissi, Nicola Dondi, Alessandro Piazza +2
We analytically determine the large central charge asymptotic expansion of the Virasoro conformal blocks entering in four-point functions with external degenerate operators on a sp…
The random free field scalar theory
Alessandro Piazza, Marco Serone, Emilio Trevisani
Quantum field theories with quenched disorder are so hard to study that even exactly solvable free theories present puzzling aspects. We consider a free scalar field in dim…
Exploring Replica-Potts CFTs in Two Dimensions
Stefanos R. Kousvos, Alessandro Piazza, Alessandro Vichi
We initiate a numerical conformal bootstrap study of CFTs with global symmetry. These include CFTs that can be obtained as coupled replicas of two-dimensional…
