Measurement of the eta'-meson mass using J/psi-->gammaeta'.

Measurement of the eta'-meson mass using J/psi-->gammaeta'.

We measure the mass of the eta;{'} meson using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector operating at the CESR e;{+}e;{-} collider. Using three decay modes, eta;{'}-->rho;{0}gamma, eta;{'}-->pi;{+}pi;{-}...
