초록

This paper presents a search for the rare flavor-changing neutral current process B-0 -> K*(0)tau(+)tau(-) using data taken with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider. The analysis is based on the entire Gamma(4S) resonance data sample of 711 fb(-1), corresponding to 772 x 10(6) B (B) over bar pairs. In our search we fully reconstruct the companion B meson produced in the process e(+)e(-) -> Gamma(4S)-> B (B) over bar from its hadronic decay modes, and look for the decay B-0 -> K-*0 tau(+)tau(-) in the rest of the event. No evidence for a signal is found. We report an upper limit on the branching fraction B(B-0 -> K*(0)tau(+)tau(-) ) < 3.1 x 10(-3) at 90% confidence level. This is the first direct limit on B(B-0 -> K*(0)tau(+)tau(-) ).
