Search for $B^{-} \to μ^{-} ν ˉ_{μ}$ Decays at the Belle Experiment

Belle Collaboration, A. Sibidanov, K. E. Varvell +184

We report the result of a search for the decay $B^{-} \to μ^{-} ν ˉ_{μ}$ . The signal events are selected based on the presence of a high momentum muon and the topology of the rest of…

Search for light tetraquark states in $Υ (1 S)$ and $Υ (2 S)$ decays

Belle Collaboration, S. Jia, C. P. Shen +192

We search for the $J^{P C} = 0^{--}$ and $1^{+-}$ light tetraquark states with masses up to 2.46~GeV/ $c^{2}$ in $Υ (1 S)$ and $Υ (2 S)$ decays with data samples of $(102 \pm 2)$ million and…

Observation of $Ξ_{c} (2930)^{0}$ and updated measurement of $B^{-} \to K^{-} Λ_{c}^{+} Λ ˉ_{c}^{-}$ at Belle

Belle Collaboration, Y. B. Li, C. P. Shen +178

We report the first observation of the $Ξ_{c} (2930)^{0}$ charmed-strange baryon with a significance greater than 5 $σ$ . The $Ξ_{c} (2930)^{0}$ is found in its decay to $K^{-} Λ_{c}^{+}$ in $…

Determination of the strong coupling constant $α_{s} (M_{Z})$ in next-to-next-to-leading order QCD using H1 jet cross section measurements

H1 collaboration, V. Andreev, A. Baghdasaryan +145

The strong coupling constant $α_{s} (M_{Z})$ is determined from inclusive jet and dijet cross sections in neutral-current deep-inelastic $e p$ scattering (DIS) measured at HERA by the H1…

Measurements of the absolute branching fractions of $B^{+} \to X_{c c ˉ} K^{+}$ and $B^{+} \to D ˉ^{(*) 0} π^{+}$ at Belle

Y. Kato, T. Iijima, I. Adachi +183

We present the measurement of the absolute branching fractions of $B^{+} \to X_{c c ˉ} K^{+}$ and $B^{+} \to D ˉ^{(*) 0} π^{+}$ decays, using a data sample of $772\times…

Measurement of the $τ$ lepton polarization and $R (D^{})$ in the decay $B ˉ \to D^{} τ^{-} ν ˉ_{τ}$ with one-prong hadronic $τ$ decays at Belle

S. Hirose, T. Iijima, I. Adachi +181

With the full data sample of $772 \times 1 0^{6}$ $B B ˉ$ pairs recorded by the Belle detector at the KEKB electron-positron collider, the decay $\bar{B} \rightarrow D^* τ^- \barν…
