Abstract

It is shown that in the decays B_c(2P)→ B_c^* γ^hard, B_c(3P)→ B_c^* γ^hard and B_c(2S)→ B_c^* +π⁺π^- followed by the decay B_c^*→ B_c +γ^soft the loss of the soft photon γ^soft do not wash out peaks from the initial excitations. The relative yields of B_c^*, 2P-wave, and 3P-wave states of B_c meson at LHC are estimated as function of transverse energy of emitted photon γ^hard. It is pointed out, that the decays B_c(2S) → B_c(B_c^*)+π⁺π^- could provide a new information about a σ resonance nature.
