| 抄録: | This paper presents the measurement of the relative width difference ΔΓ d /Γ d of the B0-B¯0 system using the data collected by the ATLAS experiment at the LHC in pp collisions at s√=7 TeV and s√=8 TeV and corresponding to an integrated luminosity of 25.2 fb−1. The value of ΔΓ d /Γ d is obtained by comparing the decay-time distributions of B 0 → J/ψK S and B 0 → J/ψK *0(892) decays. The result is ΔΓ d /Γ d = (−0.1±1.1 (stat.)± 0.9 (syst.)) × 10−2. Currently, this is the most precise single measurement of ΔΓ d /Γ d . It agrees with the Standard Model prediction and the measurements by other experiments. |
