      abstract     = {Recent years have witnessed a steady progress towards
                      blending 2D quantum materials into technology, with future
                      applications often rooted in the electronic structure. Since
                      crossings and inversions of electronic bands with different
                      orbital characters determine intrinsic quantum transport
                      properties, knowledge of the orbital character is essential.
                      Here, we benchmark angle-resolved photoelectron emission
                      spectroscopy (ARPES) as a tool to experimentally derive
                      orbital characters. For this purpose we study the valence
                      electronic structure of two technologically relevant quantum
                      materials, graphene and WSe$_2$, and focus on circular
                      dichroism that is believed to provide sensitivity to the
                      orbital angular momentum. We analyze the contributions
                      related to angular atomic photoionization profiles,
                      interatomic interference, and multiple scattering. Regimes
                      in which initial-state properties could be disentangled from
                      the ARPES maps are critically discussed and the potential of
                      using circular-dichroic ARPES as a tool to investigate the
                      spin polarization of initial bands is explored. For the
                      purpose of generalization, results from two additional
                      materials, GdMn$_6$Sn$_6$ and PtTe$_2$ are presented in
                      addition. This research demonstrates rich complexity of the
                      underlying physics of circular-dichroic ARPES, providing new
                      insights that will shape the interpretation of both past and
                      future circular-dichroic ARPES studies.},
