| dc.description | 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 ring. Branching fractions for the decays χ_c1 going to K_s^0 K^+ π^- + c.c., χ_c0 going to K_s^0 K_s^0, χ_c2 going to K_s^0 K_s^0, χ_c0 going to ϕϕ, χ_c2 going to ϕϕand χ_cJ going to K^+ K^- K^+ K^- are measured for the first time, and those for χ_cJ going to π^+ π^- π^+ π^-, $ χ_cJ going to π^+ π^- K^+ K^-, χ_cJ going to π^+ π^- p \bar{p} and χ_cJ going to 3(π^+ π^-) are measured with improved precision. In addition, we determine the masses of the χ_c0 and η_c to be M_{χ_{c0}}=3414.1 \pm 0.6(stat) \pm 0.8 (sys) MeV and M_{η_c}=2975.8 \pm 3.9(stat) \pm 1.2 (sys) MeV. | |
