Unlike heavy quarkonia, i.e. the hidden heavy quark-antiquark sectors of charmonium ($c\\bar c$) and bottomonium ($b\\bar b$), the $B_c$-mesons cannot annihilate into gluons and they are, consequently, more stable. The excited $B_c$ states, lying below the lowest strong-decay $BD$-threshold, can only undergo through radiative decays and hadronic transitions to the $B_c$ ground state, which then decays weakly.
