Measurements of Charged Current Lepton Universality and using Tau Lepton Decays to , , , and $\K^- ν_τ$
The BABAR Collaboration, B. Aubert
Using 467 of 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…
A Search for Invisible Decays of the Upsilon(1S)
The BABAR Collaboration, B. Aubert
We search for invisible decays of the Upsilon(1S) meson using a sample of 91.4 x 10^{6} Upsilon(3S) mesons collected at the BaBar/PEP-II B-factory. We select events containing the…
Improved Measurement of and Determination of the Quark-Mixing Phase Angle
B. Aubert
We present improved measurements of the branching fraction , the longitudinal polarization fraction , and the direct {\ensuremath{CP}\xspace} asymmetry {\ensuremath{…
Measurement of the e+e- --> b anti-b cross section between sqrt(S)=10.54 and 11.20 GeV
The BABAR Collaboration, B. Aubert
We report e+e- --> b anti-b cross section measurements by the BABAR experiment performed during an energy scan in the range of 10.54 to 11.20 GeV at the PEP-II e+e- collider. A tot…
Evidence for X(3872) --> psi(2S) gamma in B+/- --> X(3872) K+/- decays, and a study of B --> ccbar gamma K
The BABAR Collaboration, B. Aubert
In a search for B --> ccbar gamma K decays with the BaBar detector, where ccbar includes J/psi and psi(2S), and K includes K+, Ks, and K*(892), we find evidence for X(3872) --> J/p…
Direct CP, Lepton Flavor and Isospin Asymmetries in the Decays B->K(*)l+l-
The BABAR Collaboration, B. Aubert
We measure rate asymmetries for the rare decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-, using a sample of 384 million BBbar events collected with the Babar detector at th…
