“…[186]. Using a similar method, ATLAS and CMS have measured ∆Γ d /Γ d = (−0.1 ± 1.1 ± 0.9)% [187] and [105], respectively. Assuming Reλ CP > 0, as expected from the global fits of the Unitarity Triangle within the Standard Model [188], a combination of these six results (after adjusting the DELPHI and BABAR results to…”

“…• B 0 s → J/ψ φ decays contain a well-measured mixture of CP -even and CP -odd states. The published B 0 s → J/ψ φ effective lifetime measurements [81,105,106,127] are combined into the average τ single (B 0 s → J/ψ φ) = 1.480 ± 0.007 ps. Analyses that separate the CPeven and CP -odd components in this decay through a full angular study, outlined in Sec.…”

“…• Decays to CP eigenstates have also been measured, in the CP -even modes [124] and B 0 s → J/ψη by LHCb [131], as well as in the CP -odd modes B 0 s → J/ψ f 0 (980) by CDF [133] and D0 [134], B 0 s → J/ψ π + π − by LHCb [135] and CMS [105], and B 0 s → J/ψ K 0 S by LHCb [132]. If these decays are dominated by a single weak phase and if CP violation can be neglected, then τ single (B 0 s → CP -even) = 1/Γ sL and τ single (B 0 s → CP -odd) = 1/Γ sH (see Eqs.…”

“…With more statistics, CDF2 was able to perform the first B + c lifetime based on fully reconstructed B + c → J/ψπ + decays [141], which does not suffer from a missing neutrino. More recent measurements at the LHC, both with B + c → J/ψ µ + ν decays from LHCb [142] and B + c → J/ψ π + decays from LHCb [143] and CMS [105], achieve the highest level of precision. Two of them [105,143] are made relative to the B + lifetime.…”

Two of them [105,143] are made relative to the B + lifetime. Before averaging, they are scaled to our latest B + lifetime average, and the induced correlation is taken into account.…”
