Study of $$\mathrm{B}_{c}^{+}$$ decays to charmonia and three light hadrons
- Nikhef National Institute for Subatomic Physics, Amsterdam (Netherlands). LHCb Collaboration. et al.
Using proton-proton collision data, corresponding to an integrated luminosity of 9 fb-1 collected with the LHCb detector, seven decay modes of the $$B^+_c$$ meson into a $J/ψ$ or $ψ(2S)$ meson and three charged hadrons, kaons or pions, are studied. The decays $$B^+_c$$ → $(ψ(2S)$ →J/$ψπ^+π^-$$)$$π^+$, $$B^+_c$$→$$ψ(2S)π^+π^-π^+, B^+_c$$→ J/$ψK^+π^-π^+$ and $$B^+_c$$ → J/$ψK^+K^-K^+$ are observed for the first time, and evidence for the $$B^+_c$$ →$ψ(2S)K^+K^-π^+$, decay is found, where J/ψ and $(ψ(2S)$ mesons are reconstructed in their dimuon decay modes. The ratios of branching fractions between the different $$B^+_c$$ decays are reported as well as the fractions of the decays proceeding via intermediate resonances. The results largely support the factorisation approach used for a theoretical description of the studied decays.
