Measurement of the relative width difference of the B 0 ‐ B¯ 0 system with the ATLAS detector
Abstract: This paper presents the measurement of the relative width difference ΔΓ d /Γ d of the B 0 ‐ 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 i...
