Vector charmonium(-like) states in the energy range of 4.1-4.6 GeV
Xiang-Kun Dong, Vadim Baru, Leon von Detten +5
The spectrum of vector charmonium(-like) states in the 4.1\dash4.6~GeV energy region exhibits a long-standing tension between inclusive and exclusive measurements. While the inclus…
What can we learn from the radiative decays of the meson?
Hai-Long Fu, Feng-Kun Guo, Christoph Hanhart +1
We study the radiative decays and and argue that their simultaneous experimental measurement, or at least a…
Radiative decays of hadronic molecules: From confusion to inspiration
Feng-Kun Guo, Christoph Hanhart, Alexey Nefediev
Radiative decays of hadronic states provide an essential source of information that can facilitate deciphering their nature and properties. However, a lot of confusion concerning r…
Towards a precision determination of the parameters from data
Yi-Lin Song, Yu Zhang, Vadim Baru +3
In a recent paper, Phys. Rev. Lett. {\bf 126}, 132001 (2021), the LHCb data on the di- production in proton-proton collisions were analysed in a coupled-channel framework bas…
