Observation of Two Excited Bc+ States and Measurement of the Bc+(2S) Mass in pp Collisions at sqrt(s)=13 TeV

2019

Signals consistent with the B^+_c(2S) and B*^+_c(2S) states are observed in proton-proton collisions at √s = 13 TeV, in an event sample corresponding to an integrated luminosity of 143 fb^(-1), collected by the CMS experiment during the 2015–2018 LHC running periods. These excited bc states are observed in the B^+_cπ^+π^− invariant mass spectrum, with the ground state B^+_c reconstructed through its decay to J/ψπ^+. The two states are reconstructed as two well-resolved peaks, separated in mass by 29.1±1.5(stat)±0.7(syst) MeV. The observation of two peaks, rather than one, is established with a significance exceeding five standard deviations. The mass of the B^+_c(2S) meson is measured to be 6871.0±1.2(stat)±0.8(syst)±0.8(B+c) MeV, where the last term corresponds to the uncertainty in the world-average B^+_c mass.
