A Search for the Rare Leptonic Decays B+ -> mu+ nu and B+ -> e+ nu

N. Satoyama

We present a search for the decays B+ -> mu+ nu_mu and B+ -> e+ nu_e in a 253 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energ…

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…

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…

Time-Dependent CP Asymmetries in B0 -> Ks pi0 gamma transitions

The Belle Collaboration, Y. Ushiroda, K. Sumisawa

We report measurements of CP violation parameters in B0->Ks pi0 gamma transitions based on a data sample of 535x10^6 BB pairs collected with the Belle detector at the KEKB asymmetr…
