Non-forward scattering of twisted particles

TL;DR

This paper investigates the general scattering behavior of twisted particles, such as twisted photons, when they undergo non-forward scattering with transverse momentum transfer, extending previous studies limited to forward/backward cases.

Contribution

It introduces a comprehensive analysis of non-forward scattering processes involving twisted particles, broadening understanding beyond the previously studied forward/backward scenarios.

Findings

Characterization of kinematic features in non-forward scattering

Extension of twisted photon scattering theory to include transverse momentum transfer

Insights into potential applications in high-energy photon manipulation

Abstract

Twisted photons (i.e. photons carrying non-zero orbital angular momentum) are well-known in optics. Recently, it was suggested to use Compton backscattering off an ultra-relativistic electron beam to boost optical twisted photons into the high energy range. However, only the case of strictly forward/backward scattering has been studied so far. Here, we consider generic kinematic features of processes in which a twisted particle scatters with non-zero transverse momentum transfer.
