Neural S-matrix bootstrap II: solvable 4d amplitudes with particle production
Mehmet Asim Gumus, Damien Leflot, Piotr Tourkine +1
We study a model for nonperturbative unitarization of the four-point contact scalar amplitude in four dimensions. It is defined through an infinite sum of planar diagrams, construc…

The S-matrix bootstrap with neural optimizers I: zero double discontinuity
Mehmet Asim Gumus, Damien Leflot, Piotr Tourkine +1
In this work, we develop machine learning techniques to study nonperturbative scattering amplitudes. We focus on the two-to-two scattering amplitude of identical scalar particles,…

The flavor invariants of the SM
Christophe Grojean, Jonathan Kley, Damien Leflot +1
Sixty years after the experimental discovery of CP violation in the quark sector, the existence of a similar CP violation in the lepton sector is still to be established. Actually,…
