Measurement of b hadron lifetimes and effective lifetimes at LHCb
This paper presents two recent measurements of b-hadron lifetimes, using 1 fb$^{-1}$ of data collected by LHCb. The effective lifetime of the $B_{s} \to J/\Psi K_{S}$ decay is measured and found to be $\tau_{B_{s} \to J/\Psi K_{S}}^{\rm{eff}} = 1.75 \pm 0.12~(\rm{stat})~0.07~(\rm{syst})~\rm{ps}$. Th...
