We present new results on the lifetimes and widths of $B$ hadrons based on 300-450 pb$^{-1}$ of data collected by CDF and D{\O}at the Fermilab Tevatron. Lifetimes were measured in semileptonic decays as well as fully reconstructed hadronic…
Precision measurements of b-hadron lifetimes are a key goal of the LHCb experiment. In the B_s sector, the measurement of the effective lifetimes for B_s mesons decaying to CP-odd, CP-even and flavor specific final states are essential for…
We review the current status of theoretical predictions for mixing quantities and lifetimes in the $B$-sector. In particular, due to the first non-zero measurement of the decay rate difference in the neutral $B_s$-system, $\Delta \Gamma_s/…
Measurements of the effective lifetimes of $B_s$-meson decays, which only require untagged rate analyses, allow us to probe the width difference $\Delta\Gamma_s$ and the CP-violating phase $\phi_s$ of $B^0_s$-$\bar B^0_s$ mixing. We point…
Precision lifetime measurements of $b$-flavoured hadrons are an important test of the validity of the theoretical tool used to determine $b$-hadrons observables, the Heavy Quark Expansion. Recent measurements of the $B^+$, $\Lambda^0_b$,…
We review the theoretical status of the lifetime ratios $\tau_{B^+} / \tau_{B_d}$ and $\tau_{B_s} / \tau_{B_d}$ and of the mixing quantities $\Delta M_s$, $\Delta \Gamma_s$ and $\phi_s$. We show that the ratio $\Delta \Gamma_s / \Delta M_s$…
$B_d$ and $B_s$ meson systems play a fundamental role to test and improve our understanding of Standard Model flavor dynamics. The mixing parameters $\Delta m_{d,s}$ represent important constraints in the unitarity triangle analysis. Their…
Recent measurements of lifetimes of some $b$-flavored hadrons are presented and interpreted in the context of theoretical models, especially the Heavy Quark Expansion. Decay widths and decay width differences in the $B_s^0-\overline{B}_s^0$…
We present a calculation of 1/m^2_b corrections to the lifetime differences of B_s mesons \Delta \Gamma_s in the heavy-quark expansion. We find that they are small to significantly affect \Delta \Gamma_s and present the result for lifetime…
We present the CDF results using 1.0 fb^{-1} of data on the mixing frequency measurement in the B_s system and the lifetime measurements of several B hadrons. We obtain \Delta m_s=17.77 +- 0.1 +- 0.07 ps^{-1} and c\tau(\Lambda_b)=473.8 +-…
The Tevatron collider at Fermilab provides a very rich environment for the study of b-hadrons. Both the D0 and CDF experiments have collected a sample of about 1 fb^{-1}. We report results on three topics: b-hadron lifetimes, polarization…
The latest measurements of the masses and lifetimes of weakly decaying $B$~hadrons from experiments at $e^+e^-$ and $p\bar{p}$ colliders are presented. These measurements include the lifetimes of the $\bar{B}^0$, $\bar{B}^0_s$, $B^-$, and…
Although the B(s) and Lambda(b) hadrons differ only in the spectator quarks from the well-studied B(d) and B(u) mesons, they provide a unique window on the physics of the b-quark. With no experiments presently running at the Z pole, hadron…
