Limits on the Decay-Rate Difference of Neutral-B Mesons and on CP, T, and CPT Violation in B0-antiB0 Oscillations

B. Aubert, BABAR Collaboration

Using events in which one of two neutral-B mesons from the decay of an Y(4S) resonance is fully reconstructed, we set limits on the difference between the decay rates of the two ne…

Measurements of the mass and width of the eta_c meson and of an eta_c(2S) candidate

B. Aubert, BABAR Collaboration

The mass and total width of the eta_c meson have been measured in two-photon interactions at the SLAC asymmetric B-Factory with the BABAR detector. With a sample of approximately 2…

Rates, Polarizations, and Asymmetries in Charmless Vector-Vector B Meson Decays

The BABAR Collaboration, B. Aubert

With a sample of approximately 89 million BBbar pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (phi, rho, and…

Search for the Radiative Decays B -> rho gamma and B0 -> omega gamma

B. Aubert

A search for the exclusive radiative decays B --> rho(770) gamma and B0 --> omega(782) gamma is performed on a sample of about 84\times 10^{6} B\bar B events collected by the BaBar…

Measurements of Branching Fractions and CP-Violating Asymmetries in B0 -> rho+- h-+ Decays

B. Aubert

We present measurements of branching fractions and CP-violating asymmetries in B0 -> rho+- pi-+ and B0 -> rho- K+ decays. The results are obtained from a data sample of 88.9 10^6 U…

Observation of a Narrow Meson Decaying to Ds+pi0 at a Mass of 2.32 GeV/c^2

the BABAR Collaboration, B. Aubert

We have observed a narrow state near 2.32 GeV/c^2 in the inclusive Ds+ pi0 invariant mass distributionfrom e+e- annihilation data at energies near 10.6 GeV. The observed width is c…
