Measurement of the Lifetime of the B-c( /-) Meson in the Semileptonic Decay Channel (Art. No. 092001)

Original language description

Using approximately 1.3 fb(-1) of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the B-c( /-) meson in the B-c( /-)-} J/psi mu( /-) X final state. A simultaneous unbinned likelihood fit to the J/psi mu invariant massand lifetime distributions yields a signal of 881 /- 80(stat) candidates and a lifetime measurement of tau(B-c( /-))=0.448(-0.036)( 0.038)(stat) /- 0.032(syst) ps.
