Update of the measurement of the cross section for e^+e^- -> psi(3770) -> hadrons

D. Besson

We have updated our measurement of the cross section for e^+e^- -> psi(3770) -> hadrons, our publication "Measurement of sigma(e^+e^- -> psi(3770) -> hadrons) at E_{c.m.} = 3773 Me…

Inclusive chi_bJ(nP) Decays to D0 X

CLEO Collaboration, R. A. Briere

Using Upsilon(2S) and Upsilon(3S) data collected with the CLEO III detector we have searched for decays of chi_bJ to final states with open charm. We fully reconstruct D0 mesons wi…

First Observation of Exclusive chi_cJ Decays to Two Charged and Two Neutral Hadrons

Q. He

We study exclusive chi_c0, chi_c1 and chi_c2 decays to four-hadron final states involving two charged and two neutral mesons: pi^+pi^-pi^0pi^0, K^+K^-pi^0pi^0, pppi^0pi^0, K^+K^-et…

Precision Measurement of the Mass of the h_c(1P1) State of Charmonium

CLEO Collaboration, S. Dobbs

A precision measurement of the mass of the h_c(1P1) state of charmonium has been made using a sample of 24.5 million psi(2S) events produced in e+e- annihilation at CESR. The react…

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…

Two-Photon Widths of the chi_cJ States of Charmonium

CLEO Collaboration, K. M. Ecklund

Using a data sample of 24.5 million psi(2S) the reactions psi(2S)->gamma chi_cJ, chi_cJ->gamma gamma have been studied for the first time to determine the two-photon widths of the…
