Charm at Belle
With 10fb −1 data from Belle, the results of b to c and u decays have been represented here. Several decay modes have been studied, which include charmonium, semileptonic decay and Cabibbo-suppressed decays mode. The preliminary results and the measurements of KM matrix elements will also be presented here.
متن کاملgauge - boson production from LFV τ decays at Belle II
proposed that such a light gauge boson can be detected at the Belle II experiment with a luminosity of 50 ab−1 by the e+e− → γ + / E process through the kinetic mixing with the photon, where the missing energy / E is from the Z ′ → ν̄ν decays. We study the phenomenological implications when a pair of singlet vector-like leptons carrying different Lμ −Lτ charges are included, and a complex single...

متن کاملXsll at Belle
The electroweak penguin mediated B → Xsll decay is a good probe to study beyond the Standard Model physics at low energy. The effect of new physics could be observed as corrections to the branching fraction, di-lepton invariant mass spectrum, and to the Wilson coefficients such as C9, C10, and a phase of C7 [1-10]. Experimentally, the exclusive B → Kll decay was observed by the Belle collaborat...

unique opportunity to study the poorly-known Bs meson. Three analyses, using a sample of 23.6 fb−1, are presented. We report the first observation of the three dominant exclusive Bs decays, Bs → D∗− s π+, Bs → Ds ρ+ and Bs → D∗− s ρ+, the first observation of the CP-eigenstate decay Bs → J/ψ η , and the results from a study of the charmless Bs → K+K−, Bs → K+π−, Bs → π+π− and Bs → K0 S K0 S dec...
