- Abstract
- We measure the branching fraction of B- -> t(-)(v) over bar (t) using the full Y(4S) data sample containing 772 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. Events with B (B) over bar pairs are tagged by reconstructing one of the B mesons decaying into hadronic final states, and B- -> t(-)(v) over bar (t) candidates are detected in the recoil. We find evidence for B- -> t(-)(v) over bar (t) with a significance of 3.0 standard deviations including systematic errors and measure a branching fraction B(B- -> t(-)(v) over bar (t)) = [0: 72(-0.25)(+0.27)(stat) +/- 0.11(syst)x10(-4).
