A future gamma factory at CERN or accelerator‐based gamma sources elsewhere can include the possibility of energetic twisted photons, which are photons with a structured wave front that can allow a pre‐defined large angular momentum along the beam direction. Twisted photons are potentially a new tool in hadronic physics, and one possibility is considered here, namely the photoproduction of Δ(1232) baryons using twisted photons. It is shown that particular polarization amplitudes isolate the smaller partial wave amplitudes and they are measurable without interference from the terms that are otherwise dominant.
Twisted photons are potentially a new tool in hadronic physics; one possibility is considered in this work, namely the photoproduction of Δ(1232) baryons using twisted photons. It is shown that particular amplitudes that correspond to transfer of two units of angular momentum projection isolate the smaller electric quadrupole transition without interference from the magnetic dipole terms that are otherwise dominant.
