Search for $B^+ \to μ^+\, ν_μ$ and $B^+ \to μ^+\, N$ with inclusive tagging

M. T. Prim, F. U. Bernlochner, P. Goldenzweig, M. Heck et autres

We report the result for a search for the leptonic decay of B$^{+}$ → μ$^{+}$ν$_{μ}$ using the full Belle dataset of 711 fb$^{-1}$ of integrated luminosity at the ϒ(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and Cabibbo-Kobayashi-Maskawa suppressed. …

Measurement of the τ lepton polarization and R ( D * ) in the decay B ¯ → D * τ − ν ¯ τ with one-prong hadronic τ decays at Belle

S. Hirose, Toru Iijima, Ichiro Adachi, K. Adamczyk et autres

With the full data sample of $772\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }B\overline{B}$ pairs recorded by the Belle detector at the KEKB electron-positron collider, the decay $\overline{B}\ensuremath{\rightarrow}{D}^{*}{\ensuremath{\tau}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}}$ is studied with the hadronic $\ensuremath{\tau}$ decays ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ and ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{\ensuremath{-}}{\ensuremath{\nu}}_{\ensuremath{\tau}}$. The $\ensuremath{\tau}$ polarization ${P}_{\ensuremath{\tau}}({D}^{*})$ in two-body hadronic $\ensuremath{\tau}$ decays …

First observation of γγ→pp¯K+K− and search for exotic baryons in pK systems

C. P. Shen, C. Z. Yuan, Ichiro Adachi, H. Aihara et autres

The process $\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}p\overline{p}{K}^{+}{K}^{\ensuremath{-}}$ and its intermediate processes are measured for the first time using a $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The production of $p\overline{p}{K}^{+}{K}^{\ensuremath{-}}$ and a $\mathrm{\ensuremath{\Lambda}}(1520{)}^{0}$ $(\overline{\mathrm{\ensuremath{\Lambda}}}(1520{)}^{0})$ signal in the …
