Study of New B⁺_c Meson Decays into Charmonium and Light Hadrons in the Final State

The paper presents results of the search for new B-c(+) meson decays into charmonium and light hadrons in the final state. Relative branching fractions of the studied processes are measured. The contributions of intermediate resonant structures in light hadron systems are considered. Experimental data and theoretical predictions are compared for various mass combinations. The analysis is based on the data collected by the LHCb experiment in proton-proton collisions at the center-ofmass energies of 7, 8, and 13 TeV in the period from 2011 to 2018.
