Full Unitarity and the Moments of Scattering Amplitudes
Marc Riembau
We study the impact of full unitarity on the moment structure of forward scattering amplitudes. We introduce the semiarcs, calculable quantities in the EFT dispersively related to…

The IR-Side of Positivity Bounds
Brando Bellazzini, Marc Riembau, Francesco Riva
We show how calculable IR loop effects impact positivity bounds in Effective Field Theories with causal and unitary UV completions. We identify infrared singularities which appear…

Positive Moments for Scattering Amplitudes
Brando Bellazzini, Joan Elias Miró, Riccardo Rattazzi +2
We find the complete set of conditions satisfied by the forward scattering amplitude in unitarity and causal theories. These are based on an infinite set of energy dependen…
