Scattering amplitude annihilators [PDF]
Journal of High Energy Physics, 2020 Several second order differential operators are shown to annihilate the YM and GR tree scattering amplitudes. In particular we prove a conjecture of Loebbert, Mojaza and Plefka from their investigation of a hidden conformal symmetry in GR.

The SAGEX review on scattering amplitudes* [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Abstract This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an overview of the field, from basic aspects to a selection of current (2022) research and developments.

Positive moments for scattering amplitudes [PDF]
Physical Review D, 2021 We find the complete set of conditions satisfied by the forward $2\to2$ scattering amplitude in unitarity and causal theories. These are based on an infinite set of energy dependent quantities -- the arcs -- which are dispersively expressed as moments of a positive measure defined at (arbitrarily) higher energies.

Lévy α-Stable Model for the Non-Exponential Low-|t| Proton–Proton Differential Cross-Section
Universe, 2023 It is known that the Real Extended Bialas–Bzdak (ReBB) model describes the proton–proton (pp) and proton–antiproton (pp¯) differential cross-section data in a statistically non-excludible way, i.e., with a confidence level greater than or equal to 0.1 ...

Supergravity scattering amplitudes
Physical Review D, 2023 Supergravity theories with non-minimal Kähler potentials are characterized by a non-trivial field space manifold with corresponding non-trivial kinetic terms. The scattering amplitudes in these theories can be calculated at fixed background field values by making a field redefinition to Riemann normal coordinates.

Geometry in scattering amplitudes
Physical Review D, 2022 We formulate the field-space geometry for an effective field theory of scalars and gauge bosons. Geometric invariants such as the field-space curvature enter in both scattering amplitudes and the renormalization group equations, with the scalar and gauge results unified in a single expression.

Eikonal amplitudes from curved backgrounds
SciPost Physics, 2022 Eikonal exponentiation in QFT describes the emergence of classical physics at long distances in terms of a non-trivial resummation of infinitely many diagrams.
