Impact of Double‐π‐Bridge on Bis(Triarylamine)‐Based Organic Mixed‐Valence System: A Case Study of Diaza[1.1](4,4”) ortho ‐Terphenylophane Radical Cation

Koshi Yoshida, F. Takasaki, Masashi Uebe, Shu Seki et autres

A bis(triarylamine) (BTA) radical cation, bridged by two o-terphenylene moieties, was prepared and characterized to explore the impact of the double-π-bridge on the intramolecular charge/spin transfer process in the 2-site organic mixed-valence (MV) compound. Spectroscopic analyses on optically and thermally assisted intervalence …

Measurement of B ---> D(*) tau nu using full reconstruction tags

I. Adachi, T. Kuhr, I.-S. Cho, Y. Chao et autres

We present measurements of B -> D^* tau nu and B -> D tau nu decays using 604.5 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. Events are tagged by fully reconstructing …

High-statistics study of the τ − → π − π 0 ν τ decay

M. Fujikawa, H. Hayashii, S. Eidelman, I. Adachi et autres

We report a high-statistics measurement of the branching fraction for ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ and the invariant mass spectrum of the produced ${\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ system using $72.2\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data recorded with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The branching fraction obtained …

Study of the suppressed B meson decay B−→DK− , D→K+π−

Y. Horii, K. Trabelsi, H. Yamamoto, I. Adachi et autres

We report a study of the suppressed $B$ meson decay ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}D{K}^{\ensuremath{-}}$ followed by $D\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, where $D$ indicates a ${D}^{0}$ or ${\overline{D}}^{0}$ state. The two decay paths interfere and provide information on the $CP$-violating angle ${\ensuremath{\phi}}_{3}$. We use a data sample containing $657\ifmmode\times\else\texttimes\fi{}{10}^{6}$ …

Measurement of the moments of the photon energy spectrum in B→Xsγ decays and determination of |Vcb| and mb at Belle

C. Schwanda, P. Urquijo, E. L. Barberio, A. Limosani et autres

Using the previous Belle measurement of the inclusive photon energy in $B\ensuremath{\rightarrow}{X}_{s}\ensuremath{\gamma}$ decays, we determine the first and second moments of this spectrum for minimum photon energies in the $B$ meson rest frame ranging from 1.8 to 2.3 GeV. Combining these measurements …

We present a search for the decays ${B}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ and ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$, where ${\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ is either a ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ or ${e}^{+}{e}^{\ensuremath{-}}$ pair, with a data sample of $657\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected with the Belle detector at the KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. Signal events are reconstructed from …

Using a $492\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected near the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider, we observe the decay ${B}^{0}\ensuremath{\rightarrow}p\overline{p}{K}^{*0}$ with a branching fraction of $\mathbf{(}{1.18}_{\ensuremath{-}0.25}^{+0.29}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.11(\mathrm{syst})\mathbf{)}\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$.
