B_s Mixing and B Hadron Lifetimes at CDF
arXiv:0710.3498 · doi:10.1088/1742-6596/110/5/052038
Abstract
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 Δm_s=17.77 +- 0.1 +- 0.07 ps^{-1} and cτ(Λ_b)=473.8 +- 23.1 +- 3.5 μm. The later one is more than 3 sigma above the world average, but in reasonable agreement with HQE calculations.
