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 $…
Bounds on Abelian Currents in 4d CFTs
Denis Karateev, Petr Kravchuk, Andrea Manenti +2
We study four-dimensional conformal field theories (CFTs) with an abelian global symmetry using the conformal bootstrap approach. We obtain numerical bounds on the scaling d…
Correlation Functions and Trace Anomalies in Weakly Relevant Flows
Denis Karateev, Biswajit Sahoo
We study abstract weakly relevant flows in a general number of dimensions. They arguably provide the simplest example of renormalization group (RG) flows between two non-trivial fi…
Trace Anomalies and the Graviton-Dilaton Amplitude
Denis Karateev, Zohar Komargodski, João Penedones +1
We consider 3+1 dimensional Quantum Field Theories (QFTs) coupled to the dilaton and the graviton. We show that the graviton-dilaton scattering amplitude receives a universal contr…
Bounds on scattering of neutral Goldstones
Francesca Acanfora, Andrea Guerrieri, Kelian Häring +1
We study the space of scattering amplitudes of neutral Goldstone bosons in four space-time dimensions. We establish universal bounds on the first two non-universal Wilson…
Bounds on photon scattering
Kelian Häring, Aditya Hebbar, Denis Karateev +2
We study 2-to-2 scattering amplitudes of massless spin one particles in space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilso…
