Abstract
Using proton-proton collision data, corresponding to an integrated luminosity
of $9fb^{-1}$ collected with the LHCb detector, seven decay modes of the
$B_c^+$ meson into a $J/\psi$ or $\psi(2S)$ meson and three charged hadrons,
kaons or pions, are studied. The decays $B_c^+\rightarrow ( \psi(2S)
\rightarrow J/\psi \pi^+ \pi^-)\pi^+ $, $B_c^+\rightarrow
\psi(2S)\pi^+\pi^+\pi^-$, $B_c^+\rightarrow J/\psi K^+\pi^+\pi^-$ and
$B_c^+\rightarrow K^+K^+K^-$ are observed for the first time, and evidence for
the $B_c^+\rightarrow \psi(2S)K^+K^-\pi^+$ decay is found, where $J/\psi$ and
$\psi(2S)$ 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.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
