Study of the New Meson Decays with Charmonium and Three Light Hadrons in the LHCB Experiment.

Using proton-proton collision data, collected by the LHCb experiment and corresponding to the integrated luminosity of 9 fb−1, the several new decays to charmonium and three light charged hadrons are observed. In particular, following channels are observed → ψ(2S)π+π−π+, → (ψ(2S) → J/ψπ+π−)π+, → J/ψK+π−π+, and → J/ψK+K−K+. The first evidence of the → ψ(2S)K+K−π+ decays is obtained. The branching fractions of these decays are measured with respect to the high-statistic normalization channels. [ABSTRACT FROM AUTHOR]
