Abstract
We report Tevatron results on the meson in Run II. The meson has been observed in semileptonic decays, , by both the CDF and DØ collaborations at a significance greater than 5σ. For DØ, the candidate events are used to extract measurements of the mass and lifetime of the meson. For CDF, the observations have resulted in measurements of the relative production times branching ratio with respect to B−→J/ψK− decays and a precise determination of the lifetime of the . Also for CDF, an observation of decays at a significance exceeding 6σ results in a precise determination of the mass of the .
