| 英文摘要 | A search for the decays b-c(+) -> j/psi d-(*()0) kappa(+) and b-c(+) -> j/psi d-(*k)+*(0) is performed with data collected at the lhcb experiment corresponding to an integrated luminosity of 3 fb(-1). the decays b-c(+) -> j/psi(dk+)-k-0 and b-c(+) -> j/psi d*k-0(+) are observed for the first time, while first evidence is reported for the b-c(broken vertical bar) -> j/psi d*k-broken vertical bar(*0) and b-c(broken vertical bar) -> j/psi(dk)-k-broken vertical bar*(0) decays. the branching fractions of these decays are determined relative to the b-c(+) -> j/psi pi(+) decay. the b-c(+) mass is measured, using the j/psi(dk+)-k-0 final state, to be 6274.28 +/- 1.40(stat) +/- 0.32(syst) mev/c(2). this is the most precise single measurement of the b-c(+) mass to date. |
