Properties of the psi resonances
Description
Sharp peaks are seen in the electron-positron annihilation cross section corresponding to the psi' at 3.095 GeV and the psi' at 3.684 GeV. Cross sections for the psi and psi' decay into hadrons, e+e- pairs, and μ+μ- pairs are used to deduce the widths and quantum numbers of the psi and psi'. Studies of the decay modes are used to determine the G-parity of the psi and the existence of a two-pion cascade decay from the psi' to the psi. No other narrow resonances were found with masses between 3.2 and 7.6 GeV
