Abstract

The production of wrong sign charmed mesons b → D_(s)X, D_(s) = (D⁰, D⁺, D_s), is studied using the data collected by the DELPHI experiment in the years 1994 and 1995. Charmed mesons in Z → bb events are exclusively reconstructed by searching for the decays D⁰ → K^-π⁺, D⁺ → K^-π⁺π⁺ and D_s⁺ φπ⁺ → K⁺K^-π⁺. The wrong sign contribution is extracted by using two discriminant variables: the charge of the b-quark at decay time, estimated from the charges of identified particles, and the momentum of the charmed meson in the rest frame of the b-hadron. The inclusive branching fractions of b-hadrons into wrong sign charm mesons are measured to be: B(b → D⁰X) + B(b → D^-X) = (9.3 ± 1.7(stat) ± 1.3(syst) ± 0.4(B))%, B(b → D_s^-X) = (10.1 ± 0.4(B))%, B(b → D_s^-X) = (10.1 ± 1.0(stat) ± 0.6(syst) ± 2.8(B))% where the first error is statistical, the second and third errors are systematic.

N2 - The production of wrong sign charmed mesons b → D(s)X, D(s) = (D0, D+, Ds), is studied using the data collected by the DELPHI experiment in the years 1994 and 1995. Charmed mesons in Z → bb events are exclusively reconstructed by searching for the decays D0 → K-π+, D+ → K-π+π+ and Ds+ φπ+ → K+K-π+. The wrong sign contribution is extracted by using two discriminant variables: the charge of the b-quark at decay time, estimated from the charges of identified particles, and the momentum of the charmed meson in the rest frame of the b-hadron. The inclusive branching fractions of b-hadrons into wrong sign charm mesons are measured to be: B(b → D0X) + B(b → D-X) = (9.3 ± 1.7(stat) ± 1.3(syst) ± 0.4(B))%, B(b → Ds-X) = (10.1 ± 0.4(B))%, B(b → Ds-X) = (10.1 ± 1.0(stat) ± 0.6(syst) ± 2.8(B))% where the first error is statistical, the second and third errors are systematic.
