Measurement of the relative width difference of the B<sup>0</sup>‐B¯<sup>0</sup> system with the ATLAS detector

This paper presents the measurement of the relative width difference ΔΓ<sub>d</sub>/Γ<sub>d</sub> of the B<sup>0</sup>‐B¯<sup>0</sup> system using the data collected by the ATLAS experiment at the LHC in pp collisions at √s = 7 TeV and √s = 8 TeV and c...

description This paper presents the measurement of the relative width difference ΔΓ<sub>d</sub>/Γ<sub>d</sub> of the B<sup>0</sup>‐B¯<sup>0</sup> 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<sup>-1</sup>. The value of ΔΓ<sub>d</sub>/Γ<sub>d</sub> is obtained by comparing the decay-time distributions of B<sup>0</sup> → J/ψK<sub>S</sub> and B<sup>0</sup> → J/ψK*<sup>0</sup>(892) decays. The result is ΔΓ<sub>d</sub>/Γ<sub>d</sub> = (−0.1±1.1 (stat.)± 0.9 (syst.)) × 10<sup>-2</sup>. Currently, this is the most precise single measurement of ΔΓ<sub>d</sub>/Γ<sub>d</sub>. It agrees with the Standard Model prediction and the measurements by other experiments.
