TL;DR
This paper reports new measurements of masses and decay branching fractions of charmonium and bottomonium states using CLEO data, including identification of key singlet states and comparison with existing models.
Contribution
It provides the first identification of the eta_b(1S) state and new measurements of several charmonium and bottomonium states, advancing understanding of quarkonium spectroscopy.
Findings
Identification of eta_b(1S) state.
New mass measurements of charmonium and bottomonium states.
Comparison with theoretical models shows good agreement.
Abstract
New measurements of the masses and decay branching fractions of charmonium and bottomonium states using the data collected by the CLEO detector are presented. These include CLEO identification of the singlet states eta_c'(2S), hc(1P), and eta_b(1S). Comparison with other experimental measurements and theoretical models is also presented.
