Open String Fields as Matrices

Isao Kishimoto, Toru Masuda, Tomohiko Takahashi +1

We show that the action expanded around Erler-Maccaferri's N D-brane solution describes the N+1 D-brane system where one D-brane disappears due to tachyon condensation. String fiel…

Search for $B_{s}^{0} \to γ γ$ and a measurement of the branching fraction for $B_{s}^{0} \to ϕ γ$

Belle Collaboration, D. Dutta, B. Bhuyan +148

We search for the decay $B_{s}^{0} \to γ γ$ and measure the branching fraction for $B_{s}^{0} \to ϕ γ$ using 121.4~ $fb^{- 1}$ of data collected at the $Υ(\mathrm{…

Measurement of the $B ˉ \to X_{s} γ$ Branching Fraction with a Sum of Exclusive Decays

Belle Collaboration, T. Saito, A. Ishikawa +179

We use 772 $\times 1 0^{6}$ $B B ˉ$ meson pairs collected at the $Υ (4 S)$ resonance with the Belle detector to measure the branching fraction for $B ˉ \to X_{s} γ$ . Our me…

Quark mixing from Delta(6N^2) family symmetry

Hajime Ishimori, Stephen F. King, Hiroshi Okada +1

We consider a direct approach to quark mixing based on the discrete family symmetry Delta (6N^2) in which the Cabibbo angle is determined by a residual Z_2 times Z_2 subgroup to be…

Measurement of $B^{0} \to D_{s}^{-} K_{S}^{0} π^{+}$ and $B^{+} \to D_{s}^{-} K^{+} K^{+}$ branching fractions

J. Wiechczynski, J. Stypula, A. Abdesselam +171

We report a measurement of the $B^{0}$ and $B^{+}$ meson decays to the $D_{s}^{-} K_{S}^{0} π^{+}$ and $D_{s}^{-} K^{+} K^{+}$ final states, respectively, using $657 \times 1 0^{6} B B$ pairs col…

Continuum quasiparticle random phase approximation for astrophysical direct neutron capture reaction of neutron-rich nuclei

Masayuki Matsuo

We formulate a many-body theory to calculate the cross section of direct radiative neutron capture reaction by means of the Hartree-Fock-Bogoliubov mean-field model and the continu…
