Measurement of the eta'-meson mass using J/psi--> gamma eta'
CLEO Collaboration, J. Libby
We measure the mass of the eta' meson using psi(2S)--> pi+ pi- J/psi, J/psi--> gamma eta' events acquired with the CLEO-c detector operating at the CESR e+e- collider. Using three…
J/psi and psi(2S) Radiative Transitions to eta_c
CLEO Collaboration, R. E. Mitchell
Using 24.5 million psi(2S) decays collected with the CLEO-c detector at CESR we present the most precise measurements of magnetic dipole transitions in the charmonium system. We me…
Experimental Study of chi_b(2P) --> pi pi chi_b(1P)
C. Cawlfield, CLEO Collaboration
We have searched for the di-pion transition chi_b(2P) -> pi pi chi_b(1P) in the CLEO III sample of Upsilon(3S) decays in the exclusive decay chain: Upsilon(3S) -> gamma chi_b(2P),…
Observation of eta_c^{prime} Production in gamma gamma Fusion at CLEO
D. M. Asner, CLEO Collaboration
We report on the observation of the eta_{c}^{prime}(2^{1}S_{0}), the radial excitation of eta_{c}(1^{1}S_{0}) ground state of charmonium, in the two-photon fusion reaction gamma ga…
