Exploring Inelasticity in the S-Matrix Bootstrap
António Antunes, Miguel S. Costa, José Pereira
The modern S-Matrix Bootstrap provides non-perturbative bounds on low-energy aspects of scattering amplitudes, leveraging the constraints of unitarity, analyticity and crossing. Ty…
Lightcone Bootstrap at higher points
António Antunes, Miguel S. Costa, Vasco Goncalves +1
Higher-point functions of scalar operators are a rich observable in CFTs, as they contain OPE data involving multiple spinning operators. We derive the lightcone blocks for five- a…
Towards Bootstrapping RG flows: Sine-Gordon in AdS
António Antunes, Miguel S. Costa, João Penedones +2
The boundary correlation functions for a Quantum Field Theory (QFT) in an Anti-de Sitter (AdS) background can stay conformally covariant even if the bulk theory undergoes a renorma…
Conformal Bootstrap near the edge
António Antunes
We propose a bootstrap program for CFTs near intersecting boundaries which form a co-dimension 2 edge. We describe the kinematical setup and show that bulk 1-pt functions and bulk-…
The perturbative CFT optical theorem and high-energy string scattering in AdS at one loop
António Antunes, Miguel S. Costa, Tobias Hansen +2
We derive an optical theorem for perturbative CFTs which computes the double discontinuity of conformal correlators from the single discontinuities of lower order correlators, in a…
Numerical Methods in the Conformal Bootstrap
António Antunes
We present a low entry-level introduction to the Conformal Bootstrap. We review and obtain several basic bounds using Linear Programming in machine precision in Mathematica, making…
