Update Measurement of the b Baryon Lifetime
The lifetime of the b baryons has been measured by the ALEPH detector using two independent data samples. From a maximum likelihood fit to the impact parameter distribution of leptons in $\Lambda\ell^-$ combinations, the b baryon lifetime is measured. The lifetime of the $\Lambda_{b}^{0}$ baryon is...

| description | The lifetime of the b baryons has been measured by the ALEPH detector using two independent data samples. From a maximum likelihood fit to the impact parameter distribution of leptons in $\Lambda\ell^-$ combinations, the b baryon lifetime is measured. The lifetime of the $\Lambda_{b}^{0}$ baryon is measured from a maximum likelihood fit to the proper time distribution of $\Lambda_{c}^+\ell^-$ candidates. |
