Resumen

Four decay modes of the Bc+ meson into a J/ψ meson and multiple charged kaons or pions are studied using proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV and corresponding to an integrated luminosity of 9 fb−1. The decay Bc+→ J/ψK+Kπ+π+π is observed for the first time, and evidence for the Bc+→ J/ψ4π+ decay is found. The decay Bc+→ J/ψ3π+ is observed and the previous observation of the Bc+→ ψ(2S)π+π+π decay is confirmed using the ψ(2S) → J/ψπ+π decay mode. Ratios of the branching fractions of these four Bc+ decay channels are measured.
