${{\mathit B}_{{{s}}}^{0}}$ MEAN LIFE

INSPIRE   PDGID:
S086T
The mean ${{\mathit B}_{{{s}}}^{0}}$ lifetime is defined and computed as 1/$\Gamma _{{{\mathit B}_{{{s}}}^{0}}}$, where $\Gamma _{{{\mathit B}_{{{s}}}^{0}}}$ is the average decay width of the ${{\mathit B}_{{{s}}}^{0}}$ mass eigenstates.

1  AALTONEN 2011AP combines the fully reconstrcuted ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \pi}^{+}}$ decays and partially reconstructed ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}}{{\mathit X}}$ decays.
2  Measured using ${{\mathit D}_{{{s}}}}{{\mathit \mu}^{+}}$ vertices.
3  Uses ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}$, and ${{\mathit \phi}}{{\mathit \ell}^{+}}$ vertices.
4  Measured using ${{\mathit D}_{{{s}}}}$ hadron vertices.
5  Measured using ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}$ vertices.
6  ACKERSTAFF 1998F use fully reconstructed ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\mathit \phi}}{{\mathit \pi}^{-}}$ and ${{\mathit D}_{{{s}}}^{-}}$ $\rightarrow$ ${{\mathit K}^{*0}}{{\mathit K}^{-}}$ in the inclusive ${{\mathit B}_{{{s}}}^{0}}$ decay.
7  Combined results from ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}$ and ${{\mathit D}_{{{s}}}}$ hadron.
8  Measured using ${{\mathit \phi}}{{\mathit \ell}}$ vertices.
9  Measured using inclusive ${{\mathit D}_{{{s}}}}$ vertices.
10  Combined result for the four ABREU 1996F methods.
11  Exclusive reconstruction of ${{\mathit B}_{{{s}}}}$ $\rightarrow$ ${{\mathit \psi}}{{\mathit \phi}}$.
12  ABREU 1994E uses the flight-distance distribution of ${{\mathit D}_{{{s}}}}$ vertices, ${{\mathit \phi}}$-lepton vertices, and ${{\mathit D}_{{{s}}}}{{\mathit \mu}}$ vertices.
