Measurement of the relative width difference of the B0-B0 system with the ATLAS detector
Original language description
This paper presents the measurement of the relative width difference ΔΓd /Γd of the B0-B0 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 fb1. The value of ΔΓd /Γd is obtained by comparing the decay-time distributions of B0 J/ψKS and B0 J/ψK∗0(892) decays. The result is ΔΓd /Γd = (0.11.1 (stat.) 0.9 (syst.)) 102. Currently, this is the most precise single measurement of ΔΓd /Γd . It agrees with the Standard Model prediction and the measurements by other experiments.n
