Measurement of the masses and widths of the Σc(2455)+ and Σc(2520)+ baryons

J. Yelton, I. Adachi, J. K. Ahn, H. Aihara et autres

Using $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the Belle detector operating at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider, we report the measurements of the masses, and the first measurements of the instrinsic widths, of the ${\mathrm{\ensuremath{\Sigma}}}_{c}(2455{)}^{+}$ and ${\mathrm{\ensuremath{\Sigma}}}_{c}(2520{)}^{+}$ charmed baryons. We find …

Updated cross section measurement of e+e−→K+K−J/ψ and KS0KS0J/ψ via initial state radiation at Belle

C. P. Shen, C. Z. Yuan, P. Wang, A. Abdesselam et autres

The cross sections of the processes ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}^{+}{K}^{\ensuremath{-}}J/\ensuremath{\psi}$ and ${K}_{S}^{0}{K}_{S}^{0}J/\ensuremath{\psi}$ are measured via initial state radiation at center-of-mass energies between the threshold and 6.0 GeV using a data sample of $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the Belle detector on or near the $\mathrm{\ensuremath{\Upsilon}}(nS)$ …

Study of exclusive B → X u ℓ ν decays and extraction of | V u b | using full reconstruction tagging at the Belle experiment

A. Sibidanov, K. E. Varvell, I. Adachi, H. Aihara et autres

We report the results of a study of the exclusive semileptonic decays ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$, ${\overline{B}}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$, ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$, ${\overline{B}}^{0}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$ and ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\ell}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\ell}}$, where $\ensuremath{\ell}$ represents an electron or a muon. The events are tagged by fully reconstructing a second $B$ meson in the event in a …

Evidence for B−→τ−ν¯τ with a Hadronic Tagging Method Using the Full Data Sample of Belle

K. Hara, Y. Horii, T. Iijima, I. Adachi et autres

We measure the branching fraction of ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\tau}}^{\ensuremath{-}}{\overline{\ensuremath{\nu}}}_{\ensuremath{\tau}}$ using the full $\ensuremath{\Upsilon}(4S)$ data sample containing $772\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. Events with $B\overline{B}$ pairs are tagged by reconstructing one of the $B$ mesons decaying …

Dalitz analysis of the three-body charmless decays B+→K+π+π− and B+→K+K+K−

A. Garmash, K. Abe, H. Aihara, M. Akatsu et autres

We report results on the Dalitz analysis of three-body charmless ${B}^{+}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ and ${B}^{+}\ensuremath{\rightarrow}{K}^{+}{K}^{+}{K}^{\ensuremath{-}}$ decays based on a $140{\text{ }\text{ }\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected with the Belle detector. Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: ${B}^{+}\ensuremath{\rightarrow}{f}_{0}(980){K}^{+}$, ${B}^{+}\ensuremath{\rightarrow}{K}_{0}^{*}(1430{)}^{0}{\ensuremath{\pi}}^{+}$, and to vector-pseudoscalar …

Search for the electric dipole moment of the τ lepton

K. Inami, K. Abe, K. Abe, R. Abe et autres

We have searched for a CP violation signature arising from an electric dipole moment (dτ) of the τ lepton in the e+e−→τ+τ− reaction. Using an optimal observable method and 29.5 fb−1 of data collected with the Belle detector at the KEKB collider …
