The observation possibility of $B_c$ excitations at LHC

A. V. Berezhnoy, A. K. Likhoded

It is shown that in the decays $B_c(2P)\to B_c^{\ast }{\gamma }^{\mathrm{hard}}$, $B_c(3P)\to B_c^{\ast }{\gamma }^{\mathrm{hard}}$ and $B_c(2S)\to B_c^{\ast }+{\pi }^{+}{\pi }^{-}$ followed by the decay $B_c^*\to B_c +γ^\mathrm{…
