Double Compton scattering of high-energy twisted photons is investigated within the framework of relativistic quantum electrodynamics. We investigate the dependence of the angular distributions of the scattered photons on the parameters of the incident photon beam, such as momentum cone opening angle and projection of orbital angular momentum. Numerical calculations of the angular distributions of the scattered photons are presented for incoming twisted photons and compared to the standard case of incident plane-wave photons. The dependence of the angular distributions of the double-Compton-scattered photons for initially twisted photons prepared in a superposition of two vortex states is also presented.
