Scattering of ultrashort electron wave packets: optical theorem, differential phase contrast and angular asymmetries

New Journal of Physics
Recent advances in electron microscopy allowed the generation of high-energy electron wave packets of ultrashort duration. Here we present a non-perturbative S -matrix theory for scattering of ultrashort electron wave packets by atomic targets.

A QCD interpretation of the scaling observed in the LHC proton-proton elastic cross-sections at moderate transfer momentum

Nuclear Physics B
A phenomenological scaling property of the LHC proton-proton elastic scattering cross sections at moderate transfer momentum has been recently observed.

Worldline geometries for scattering amplitudes

Journal of High Energy Physics
Abstract In this paper, we construct the path integral for infinite and semi-infinite scalar worldlines. We show that, at the asymptotic endpoints, on-shell physical states can be generated by inserting vertex operators at infinity.

The S-matrix bootstrap with neural optimizers. Part I. Zero double discontinuity

Journal of High Energy Physics
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 and study a toy model where we set the double discontinuity to zero ...

Positivity properties of scattering amplitudes

Journal of High Energy Physics
Abstract We investigate positivity properties in quantum field theory (QFT). We provide evidence, and in some case proofs, that many building blocks of scattering amplitudes, and in some cases the full amplitudes, satisfy an infinite number of positivity conditions: the functions, as well as all their signed derivatives, are non ...
