Abstract

In a data sample of about four million hadronic Z decays recorded with the ALEPH detector from 1991 to 1995, the B(s)/⁰→D(s)/((*))⁺D(s)/((*))^- decay is observed, based on tagging the final state with two φ mesons in the same hemisphere. The D(s)/((*))⁺D(s)/((*))^- final state is mostly CP even and corresponds to the short-lived B(s)/⁰ mass eigenstate. The branching ratio of this decay is measured to be BR(B(s)/⁰(short) → D(s)/((*))⁺D(s)/((*))^-) = (23 ± 10_-9/⁺¹⁹)%. A measurement of the lifetime of the B(s)/⁰(short) gives 1.27 ± 0.33 ± 0.08 ps. The lifetime and branching ratio measurements provide two essentially independent methods of estimating the relative decay width difference ΔΓ/Γ in the B(s)/⁰-B̄(s)/⁰ system, corresponding to an average value ΔΓ/Γ = (25_-14/⁺²¹)%.

N2 - In a data sample of about four million hadronic Z decays recorded with the ALEPH detector from 1991 to 1995, the B(s)/0→D(s)/((*))+D(s)/((*))- decay is observed, based on tagging the final state with two φ mesons in the same hemisphere. The D(s)/((*))+D(s)/((*))- final state is mostly CP even and corresponds to the short-lived B(s)/0 mass eigenstate. The branching ratio of this decay is measured to be BR(B(s)/0(short) → D(s)/((*))+D(s)/((*))-) = (23 ± 10-9/+19)%. A measurement of the lifetime of the B(s)/0(short) gives 1.27 ± 0.33 ± 0.08 ps. The lifetime and branching ratio measurements provide two essentially independent methods of estimating the relative decay width difference ΔΓ/Γ in the B(s)/0-B̄(s)/0 system, corresponding to an average value ΔΓ/Γ = (25-14/+21)%.
