Measurement of Branching Fractions for B → χ c 1 ( 2 ) K ( K ∗ ) at Belle Belle
We have measured the branching fractions for the exclusive decay modes B → χc1(2)K(K ∗) using a 140 fb data sample collected by the Belle detector at the KEKB asymmetric-energy e+e− collider. The measured branching fractions for B+ → χc1K, B0 → χc1K, B0 → χc1K and B+ → χc1K decay modes are (4.5 ± 0.2 ± 0.5) × 10−4, (3.5 ± 0.3 ± 0.5) × 10−4, (3.1 ± 0.3 ± 0.7) × 10−4 and (4.1 ± 0.6 ± 0.9) × 10−4,...
متن کاملCharm 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...
