Study of the Hadronic Decays of χ_c States
J. Z. Bai
Hadronic decays of the P-wave spin-triplet charmonium states χ_cJ (J=0,1,2) are studied using a sample of ψ(2S) decays collected by the BES detector operating at the BEPC storage r…
Fragmentation and Multifragmentation of 10.6A GeV Gold Nuclei
EMU01-Collaboration
We present the results of a study performed on the interactions of 10.6A GeV gold nuclei in nuclear emulsions. In a minimum bias sample of 1311 interac- tions, 5260 helium nuclei a…
Determination of the J/psi Leptonic Branching Fraction via psi(2S) -> pi^+ pi^- J/psi
J. Z. Bai
A comparison of the rates for psi(2S) -> pi^+ pi^- J/psi, J/psi -> l^+l^- and J/psi -> anything is used to determine the J/psi leptonic branching fractions. The results are B(J/psi…
Branching Fractions for and
J. Z. Bai
We report the first measurements of the branching fractions: and . The $…
