| 英文摘要 | We report an observation of the decay B-0 -> D*-tau(+)nu(tau) in a data sample containing 535x10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We find a signal with a significance of 5.2 sigma and measure the branching fraction B(B-0 -> D*-tau(+)nu(tau))=(2.02(-0.37)(+0.40)(stat)+/- 0.37(syst))%. This is the first observation of an exclusive B decay with a b -> c tau nu(tau) transition. |
