Four decay modes of the

+
$$ {B}_c^{+} $$
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

$$ {B}_c^{+} $$

c
+
$$ {B}_c^{+} $$

$$ {B}_c^{+} $$
