Description
A search for the excited Bc meson states is performed using 20 fb-1 of 8 TeV pp collision data collected by ATLAS in 2012. It was done using a partially reconstructed semileptonic Bc decay mode. Having 20 times larger branching ratio, than fully reconstructed hadron Bc decay channel, this mode seems to give an unique ability for searching excited states, using mass difference technique. The structure observed in mass – difference distribution is consistent with previously discovered Bc(2S) state.
