| Resumen | Using approximately 1.3fb-1 of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the Bc± meson in the Bc±→J/ψμ±+X final state. A simultaneous unbinned likelihood fit to the J/ψ+μ invariant mass and lifetime distributions yields a signal of 881±80(stat) candidates and a lifetime measurement of τ(Bc±)=0.448+0.038-0.036(stat)±0.032(syst)ps. |
