Lévy α-Stable Model for the Non-Exponential Low-|t| Proton–Proton Differential Cross-Section

open access: yesUniverse, 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

open access: yesSciPost 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

open access: yesPhysics 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

Scattering amplitude annihilators

open access: yesJournal 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

open access: yesJournal 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.

Tidal effects for spinning particles

open access: yesJournal of High Energy Physics, 2021
Expanding on the recent derivation of tidal actions for scalar particles, we present here the action for a tidally deformed spin-1/2 particle. Focusing on operators containing two powers of the Weyl tensor, we combine the Hilbert series with an on-shell ...

Wave-scattering from a gently curved surface

open access: yesPhysics Letters B, 2016
We study wave scattering from a gently curved surface. We show that the recursive relations, implied by shift invariance, among the coefficients of the perturbative series for the scattering amplitude allow to perform an infinite resummation of the ...

Complex forward scattering coefficient for signal characterisation

open access: yesThe Journal of Engineering, 2019
In this study, modelling and characteristics analysis of forward scattering coefficients and echoes are investigated. Traditional ground-target forward scattering signal model has not considered the impact of scattering phase; thus it is not accurate ...

Contra-intuitive features of time-domain Brillouin scattering in collinear paraxial sound and light beams

open access: yesPhotoacoustics, 2020
Time-domain Brillouin scattering is an opto-acousto-optical probe technique for the evaluation of transparent materials. Via optoacoustic conversion, ultrashort pump laser pulses launch coherent acoustic pulses in the sample.
