Comment on "Observation of a New chib State in Radiative Transitions to Upsilon1S and Upsilon2S at ATLAS"
Abstract
We comment on the recent observation of chib states by the ATLAS Collaboration and contest their peremptory interpretation of the highest of the three observed structures as the chib(3P) system. Moreover, we do not agree that from their data the mass barycenter of the chib(3P) system can be determined.
