Measurement of partial branching fractions of inclusive charmless B meson decays to K+, K0, and pi+

The BABAR Collaboration, P. del Amo Sanchez

We present measurements of partial branching fractions of $B \to K^{+} X$ , $B \to K^{0} X$ , and $B \to π^{+} X$ , where $X$ denotes any accessible final state abov…

Analysis of the D+ --> K- pi+ e+ nu_e decay channel

The BABAR Collaboration, P. del Amo Sanchez

Using 347.5 fb-1 of data recorded by the BABAR detector at the PEP-II electron-positron collider, 244*10^3 signal events for the D+ --> K- pi+ e+ nu_e decay channel are analyzed. T…

Measurement of the Absolute Branching Fractions for $D_{s}^{-} \to ℓ^{-} ν ˉ_{ℓ}$ and Extraction of the Decay Constant $f_{D_{s}}$

The BABAR Collaboration, P. del Amo Sanches

The absolute branching fractions for the decays $D_{s}^{-} \to ℓ^{-} ν ˉ_{ℓ}$ ( $ℓ = e$ , $μ$ , or $τ$ ) are measured using a data sample corresponding to an integrated lum…

Measurement of the gamma gamma* --> eta_c transition form factor

The BABAR Collaboration, J. P. Lees

We study the reaction e+e- --> e+e- eta_c, eta_c --> K_S K+- pi-+ and obtain eta_c mass and width values 2982.2+-0.4+-1.6 MeV/c^2 and 31.7+-1.2+-0.8 MeV, respectively. We find Gamm…

Test of lepton universality in Upsilon(1S) decays at BaBar

The BABAR Collaboration, P. del Amo Sanchez

The ratio $R_{τ μ} (Υ (1 S)) = Γ_{Υ (1 S) \to τ^{+} τ^{-}} / Γ_{Υ (1 S) \to μ^{+} μ^{-}}$ is measured using a sample of $(121.8 \pm 1.2) \times 1 0^{6}$ $Υ (3 S)$ events recorded by the BABAR detector. This measur…
