Title: $$B^{0}_{s}$$ Lifetime Measurement in the CP-odd Decay Channel $$B^{0}_{s} \to J/\psi\mbox{ }f_{0}(980)$$

Abstract

Here, the lifetime of the B_s⁰ meson is measured in the decay channel B_s⁰→J/ψπ⁺π^- with 880 ≤ M_π+π- ≤ 1080 MeV/c², which is mainly a CP-odd state and dominated by the f₀(980) resonance. In 10.4 fb^-1 of data collected with the D0 detector in Run II of the Tevatron, the lifetime of the B_s⁰ meson is measured to be τ(B_s⁰) = 1.70 ± 0.14(stat) ± 0.05(syst) ps. Neglecting CP violation in B_s⁰/$$\bar{B}$$⁰_s mixing, the measurement can be translated into the width of the heavy mass eigenstate of the B_s⁰, Γ_H = 0.59 ± 0.05(stat) ± 0.02(syst) ps^-1.

Measurement of branching ratio and B⁰_s lifetime in the decay B⁰_s → J/ψ f₀(980) at CDF

Journal Article Aaltonen, T. - Physical Review. D, Particles, Fields, Gravitation and Cosmology

We present a study of Bs0 decays to the CP-odd final state J/ψ f₀(980) with J/ψ → µ⁺µ^- and f₀(980) → π⁺π^-. Using pp̄ collision data with an integrated luminosity of 3.8 fb^-1 collected by the CDF II detector at the Tevatron we measure a Bs0 lifetime of τ(B⁰_s → J/ψ f₀(980)) = 1.70_-0.11^+0.12(stat) ± 0.03(syst) ps. This is the first measurement of the Bs0} lifetime in a decay to a CP eigenstate and corresponds in the standard model to the lifetime of the heavy Bs0 eigenstate. We also measure the product of branching fractions of B⁰_s → J/ψ f₀(980)more »« less

Measurement of the B⁰_s lifetime in B⁰_s → K⁺ K^- decays

Thesis/Dissertation Pounder, Nicola Louise

A method is presented to simultaneously separate the contributions to a sample of B⁰_s → h⁺h^'- decays, where h = π or K, and measure the B meson lifetimes in the sample while correcting for the bias in the lifetime distributions due to the hadronic trigger at the CDF experiment. Using 1 fb^-1 of data collected at CDF the B⁰ lifetime is measured as τ_B⁰ = 1.558_-0.047^+0.050_stat ± 0.028_syst ps, in agreement with the world average measurement. The B⁰_s lifetime in the B_s⁰ → K⁺K^- decay is measured as τ_{B⁰_s} → K⁺K^- = 1.51_-0.11^+0.13_stat ± 0.04 _syst ps. Nomore »« less
