Title: Search for the decay B 0 → K * 0 τ + τ − at the Belle experiment

Abstract

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