Mass, total and two-photon decay widths of the ηc meson
Description
I will present recent measurements of the mass, total and two-photon decay widths of the ηc meson. The world average of the total decay width measurements have been substantially smaller than the theoretically expected value, but new measurements bring them into better agreement. The two-photon decay width sheds new light on the disagreement between experimental measurements and the QCD prediction for the rate of the radiative decay J/ψ → γηc. (author)
