Measurements of Charged Current Lepton Universality and $∣ V_{u s} ∣$ using Tau Lepton Decays to $e^{-} ν ˉ_{e} ν_{τ}$ , $μ^{-} ν ˉ_{μ} ν_{τ}$ , $π^{-} ν_{τ}$ , and $\K^- ν_τ$

The BABAR Collaboration, B. Aubert

Using 467 $f b^{- 1}$ of $e^{+} e^{-}$ annihilation data collected with the BaBar detector, we measure $\frac{\cal{B}(τ^- \to μ^- \barν_μν_τ)}{\cal{B}(τ^- \to e^- \barν_e ν_τ)} = (0.9796…

Measurements of the $τ$ Mass and Mass Difference of the $τ^{+}$ and $τ^{-}$ } at BaBar

The BaBar Collaboration, B. Aubert

We present the result from a precision measurement of the mass of the $τ$ lepton, $M_{τ}$ , based on $423 f b^{- 1}$ of data recorded at the $Υ (4 S)$ resonance with the BaBar detector. U…

Time-dependent amplitude analysis of B0 --> K0S pi+ pi-

The BABAR Collaboration, B. Aubert

We perform a time-dependent amplitude analysis of $B^{0} \to K_{S}^{0} π^{+} π^{-}$ decays to extract the CP violation parameters of $f_{0} (980) K_{S}^{0}$ and $ρ^{0} (770) K_{S}^{0}$ and the direct CP asy…

Search for B^0 Meson Decays to π^0 K^0_SK^0_S, ηK^0_S K^0_S, and η^{\prime}K^0_SK^0_S

The BABAR Collaboration, B. Aubert

We describe searches for $B^{0}$ meson decays to the charmless final states $π^{0} K_{S}^{0} K_{S}^{0}$ , $η K_{S}^{0} K_{S}^{0}$ , and $η^{'} K_{S}^{0} K_{S}^{0}$ . The data sample corresponds to $467 \times 1…

Search for b-> u transitions in B0 -> D0 K*0 decays

The BABAR Collaboration, B. Aubert

We present a study of the decays B0 -> D0 K*0 and B0 -> barD0 K*0 with K*0 -> K+pi-. The D0 and the barD0 mesons are reconstructed in the final states f=K+pi-, K+pi-pi0, K+pi-pi+pi…
