lifetime measurement in the -odd decay channel

· Physical Review D
Here, the lifetime of the B$$0\atop{S}$$ meson is measured in the decay channel B$$0\atop{S}$$→J/ψπ+π- with 880 ≤ Mπ+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$$0\atop{S}$$ meson is measured to be τ(B$$0\atop{S}$$) = 1.70 ± 0.14(stat) ± 0.05(syst) ps. Neglecting CP violation in B$$0\atop{S}/$$\bar{B}$0s mixing, the measurement can be translated into the width of the heavy mass eigenstate of the B$$0\atop{S}$$, ΓH = 0.59 ± 0.05(stat) ± 0.02(syst) ps-1.
