Observation of decays to and $π^+π^-\e^+e^-$

CLEO Collaboration, P. Naik

Using psi(2S) --> pi+ pi- J/psi, J/psi --> gamma eta' events acquired with the CLEO-c detector at the CESR e+e- collider, we make the first observations of the decays eta' --> pi+…

Observation of J/psi --> 3 gamma

CLEO Collaboration, G. S. Adams

We report the first observation of the decay J/psi --> 3 gamma. The signal has a statistical significance of 6 sigma and corresponds to a branching fraction of B(J/psi --> 3 gamma)…

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…

First Observation of the Decay D_s^+ to proton anti-neutron

CLEO Collaboration, S. B. Athar

Using e^+e^- -> D_s^*+ D_s^- data collected near the peak D_s production energy, E_cm=4170 MeV, with the CLEO-c detector, we present the first observation of the decay D_s^+ -> pro…

Absolute Branching Fractions of Cabibbo-Suppressed D --> K Kbar Decays

CLEO Collaboration, G. Bonvicini

Using 281/pb of data collected with the CLEO-c detector at the psi(3770) resonance, we have studied Cabibbo-suppressed decays of D mesons to final states with two kaons. We present…
