Abstract

Oscillations of B0 s mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: B0 s → D- sπ+ or D- sa+ 1 and B0 s → D̄0K-π+ or D̄0K-a+ 1, where the D decays are completely reconstructed. In addition. B0 s-B0 s̄ oscillations have been studied in events with an exclusively reconstructed Ds accompanied in the same hemisphere by a high momentum hadron of opposite charge. Combining the two analyses, a limit on the mass difference between the physical B0 s states has been obtained: ΔmB0s > 4.0 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 3.2 ps-1. Using the latter sample of events, the B0 s lifetime has been measured and an upper limit on the decay width difference between the two physical B0 s states has been obtained: τB0s = 1.53+0.16 -0.15(stat.) ± 0.07(syst.) ps ΔΓB0sB0s <0.69 at the 95% C.L. The combination of these results with those obtained using D± s sample gives: ΔmB0s > 4.9 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 8.7 ps-1. τB0s = 1.46 ± 0.11 ps and ΔΓB0sB0s <0.45 at the 95% C.L.

title = "Study of B0 s-B0 s̄ oscillations and B0 s lifetimes using hadronic decays of B0 s mesons",
abstract = "Oscillations of B0 s mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: B0 s → D- sπ+ or D- sa+ 1 and B0 s → D̄0K-π+ or D̄0K-a+ 1, where the D decays are completely reconstructed. In addition. B0 s-B0 s̄ oscillations have been studied in events with an exclusively reconstructed Ds accompanied in the same hemisphere by a high momentum hadron of opposite charge. Combining the two analyses, a limit on the mass difference between the physical B0 s states has been obtained: ΔmB0s > 4.0 ps-1 at the 95{\%} C.L. with a sensitivity of ΔmB0s = 3.2 ps-1. Using the latter sample of events, the B0 s lifetime has been measured and an upper limit on the decay width difference between the two physical B0 s states has been obtained: τB0s = 1.53+0.16 -0.15(stat.) ± 0.07(syst.) ps ΔΓB0s/ΓB0s <0.69 at the 95{\%} C.L. The combination of these results with those obtained using D± sℓ∓ sample gives: ΔmB0s > 4.9 ps-1 at the 95{\%} C.L. with a sensitivity of ΔmB0s = 8.7 ps-1. τB0s = 1.46 ± 0.11 ps and ΔΓB0s/ΓB0s <0.45 at the 95{\%} C.L.",

N2 - Oscillations of B0 s mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: B0 s → D- sπ+ or D- sa+ 1 and B0 s → D̄0K-π+ or D̄0K-a+ 1, where the D decays are completely reconstructed. In addition. B0 s-B0 s̄ oscillations have been studied in events with an exclusively reconstructed Ds accompanied in the same hemisphere by a high momentum hadron of opposite charge. Combining the two analyses, a limit on the mass difference between the physical B0 s states has been obtained: ΔmB0s > 4.0 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 3.2 ps-1. Using the latter sample of events, the B0 s lifetime has been measured and an upper limit on the decay width difference between the two physical B0 s states has been obtained: τB0s = 1.53+0.16 -0.15(stat.) ± 0.07(syst.) ps ΔΓB0s/ΓB0s <0.69 at the 95% C.L. The combination of these results with those obtained using D± sℓ∓ sample gives: ΔmB0s > 4.9 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 8.7 ps-1. τB0s = 1.46 ± 0.11 ps and ΔΓB0s/ΓB0s <0.45 at the 95% C.L.
