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.

Dual superconformal symmetry of N $$ \mathcal{N} $$ = 2 Chern-Simons theory with fundamental matter at large N [PDF]
Journal of High Energy Physics, 2019 Dual conformal symmetry and Yangian symmetry are symmetries of amplitudes that have aided the study of scattering amplitudes in highly supersymmetric theories like N $$ \mathcal{N} $$ = 4 SYM and ABJM.

Analyticity properties of scattering amplitude in theories with compactified space dimensions
Nuclear Physics B, 2019 We consider a massive scalar, neutral, field theory in a five dimensional flat spacetime. Subsequently, one spatial dimension is compactified on a circle, S1, of radius R.

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.

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 ...

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.

Novel corrections to the momentum sum rule for nuclear structure functions
Physics Letters B, 2022 We address novel features of deep inelastic lepton scattering on nuclei at small Bjorken variable xBj. In this regime the lepton-nuclear cross section involves the interference between the standard lepton-quark scattering amplitude for the deep inelastic

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.

The amplitude for classical gravitational scattering at third Post-Minkowskian order
Journal of High Energy Physics, 2021 We compute the scattering amplitude for classical black-hole scattering to third order in the Post-Minkowskian expansion, keeping all terms needed to derive the scattering angle to that order from the eikonal formalism.
