Search for Invisible Decay of the $Υ (1 S)$

The Belle Collaboration, O. Tajima, H. Hayashii +4

We report results of a search for the invisible decay of the Upsilon(1S) via the Upsilon(3S)->pi+pi-Upsilon(1S) transition using a data sample of 2.9 fb^{-1} at the Upsilon(3S) res…

Search for Lepton Flavor Violating Decays $τ^{\pm} \to ℓ^{\pm} π^{0}, ℓ^{\pm} η, ℓ^{\pm} η^{'}$

The BABAR Collaboration, B. Aubert

A search for lepton flavor violating decays of the $τ$ lepton to a lighter mass lepton and a pseudoscalar meson has been performed using 339 fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data…

Measurements of exclusive B_s^0 decays at the Y(5S) resonance

A. Drutskoy

Several exclusive $B_{s}^{0}$ decays are studied using a 1.86 fb-1 data sample collected at the Y(5S) resonance with the Belle detector at the KEKB asymmetric energy e^+ e^- collider.…

The first observation of $τ^{\pm} \to ϕ K^{\pm} ν$ decay

Belle Collaboration

We present the first measurement of tau-decays to hadronic final states with a $ϕ$ -meson. This is based on 401.4 fb $^{- 1}$ of data accumulated at the Belle experiment. The branchin…

Measurement of the near-threshold $e^{+} e^{-} \to D^{() \pm} D^{\mp}$ cross section using initial-state radiation

Belle Collaboration

We report a measurement of the exclusive $e^{+} e^{-} \to D^{(*) \pm} D^{*\mp}$ cross section as a function of center-of-mass energy near the $D^{(*)^{\pm}} D^{*\mp}$ threshold wit…

Measurement of Forward-Backward Asymmetry and Wilson Coefficients in $B \to K^{*} ℓ^{+} ℓ^{-}$

A. Ishikawa

We report the first measurement of the forward-backward asymmetry and the ratios of Wilson coefficients $A_{9} / A_{7}$ and $A_{10} / A_{7}$ in $B \to K^{*} ℓ^{+} ℓ^{-}$ , where $ℓ$ repres…
