Abstract

The lifetime of the Bs0 meson is measured in the decay channel Bs0→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 Bs0 meson is measured to be τ(Bs0)=1.70±0.14(stat)±0.05(syst) ps. Neglecting CP violation in Bs0/Bs0 mixing, the measurement can be translated into the width of the heavy mass eigenstate of the Bs0, ΓH=0.59±0.05(stat)±0.02(syst) ps-1.
