Central elastic scattering

Physics Letters B, 2021
We comment on phase selection of the scattering amplitude, emphasizing that the elastic overlap function should have a central impact parameter profile at high energies and highlighting the role of the reflective scattering mode at the LHC energies ...

Spinning waveforms of scalar radiation in quadratic modified gravity

European Physical Journal C: Particles and Fields
We study scalar–tensor gravitational theories using on-shell amplitude methods. We focus on theories with gravity coupled to a massless scalar via the Gauss–Bonnet and Chern–Simons terms. In this framework, we calculate the waveforms for classical scalar

Splitting CEGM amplitudes

Journal of High Energy Physics
The CEGM formalism offers a general framework for scattering amplitudes, which rests on Grassmannians, moduli spaces and tropical geometry. The physical implications of this generalization are still to be understood.

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 ...
