Search for Bbar --> Lambda_c+ X l- nu Decays in Events With a Fully Reconstructed B Meson

The BABAR Collaboration, J. P. Lees

We present a search for semileptonic B decays to the charmed baryon Lambda_c+ based on 420 fb-1 of data collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II…

Search for the Decay D0 -> gamma gamma and Measurement of the Branching Fraction for D0 -> pi0 pi0

The BABAR Collaboration, J. P. Lees, others

We search for the rare decay of the $D^{0}$ meson to two photons, $D^{0} \to γ γ$ , and present a measurement of the branching fraction for a $D^{0}$ meson decaying to two neutra…

Search for CP violation using $T$ -odd correlations in $D^{+} \to K^{+} K_{S}^{0} π^{+} π^{-}$ and $D_{s}^{+} \to K^{+} K_{S}^{0} π^{+} π^{-}$ decays

The BABAR Collaboration, J. P. Lees

We search for CP violation in a sample of 20000 Cabibbo-suppressed decays, $D^{+} \to K^{+} K_{S}^{0} π^{+} π^{-}$ , and 30000 Cabibbo-favored decays, $D_{s}^{+} \to K^{+} K_{S}^{0} π^{+} π^{-}$ . We…

Measurement of the mass and width of the Ds1(2536)+ meson

The BABAR Collaboration, J. P. Lees

The decay width and mass of the Ds1(2536)+ meson are measured via the decay channel Ds1+ -> D*+KS0 using 385 fb^-1 of data recorded with the BABAR detector in the vicinity of the Y…

Measurement of the gamma gamma* --> eta and gamma gamma* --> eta' transition form factors

The BABAR Collaboration

We study the reactions e+e- --> e+e- eta (eta') in the single-tag mode and measure the gamma gamma* --> eta (eta') transition form factors in the momentum transfer range from 4 to…
