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.
