Multipolar transitions excited by twisted photons in heavy quarkonia
P. S. Korolev, V. A. Ryakin
In this study, we investigate the excitation of multipole transitions in quarkonium systems by high-energy photons carrying orbital angular momentum. We derive explicit expressions…

Observation of transition radiation carrying orbital angular momentum
Y. Takabayashi, H. Takeda, E. Magome +5
Twisted photons carrying orbital angular momentum, which have potential applications spanning diverse fields, have been extensively studied since the theoretical work of Allen \tex…
