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 amplitude for classical gravitational scattering at third Post-Minkowskian order [PDF]
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.

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.

Chaotic scattering of highly excited strings [PDF]
Journal of High Energy Physics, 2021 Motivated by the desire to understand chaos in the S-matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for scattering of light strings have been a hallmark of string theory since its

Second-order post-Minkowskian scattering in arbitrary dimensions [PDF]
Journal of High Energy Physics, 2020 We extract the long-range gravitational potential between two scalar particles with arbitrary masses from the two-to-two elastic scattering amplitude at 2nd Post-Minkowskian order in arbitrary dimensions.

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.

Chaos in a Many-String Scattering Amplitude. [PDF]
Physical Review Letters, 2021 String theory provides a compact integral expression for the tree-level scattering amplitude of an arbitrary number of light strings. We focus on amplitudes involving a few tachyons and many photons, with a special choice of polarizations and kinematics.

A scattering amplitude in Conformal Field Theory [PDF]
Journal of High Energy Physics, 2020 We define form factors and scattering amplitudes in Conformal Field Theory as the coefficient of the singularity of the Fourier transform of time-ordered correlation functions, as p2 → 0.

Energy-Dependent π^{+}π^{+}π^{+} Scattering Amplitude from QCD.
Physical Review Letters, 2021 Focusing on three-pion states with maximal isospin (π^{+}π^{+}π^{+}), we present the first nonperturbative determination of an energy-dependent three-hadron scattering amplitude from first-principles QCD.

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 ...
