• #### Measurement of the $B→\overline{D}^{(*)}D^{(*)}K$ Branching Fractions ﻿

(American Physical Society (APS), 2011)
We present a measurement of the branching fractions of the 22 decay channels of the $B^0$ and $B^+$ mesons to $\overline{D}^{(*)}D^{(*)}K$, where the $D^{(*)}$ and $\overline{D}^{(*)}$ mesons are fully reconstructed. ...
• #### Observation of η_{c}(1S) and η_{c}(2S) decays to K^{+}K^{-}π^{+}π^{-}π^{0} in two-photon interactions ﻿

(American Physical Society (APS), 2011)
We study the processes γγ→K0SK±π∓ and γγ→K+K−π+π−π0 using a data sample of 519.2fb−1 recorded by the BABAR detector at the PEP-II asymmetric-energy e+e− collider at center-of-mass energies near the Υ(nS) (n=2, 3, 4) ...
• #### Search for b→u transitions in B^{±}→[K^{∓}π^{±}π^{0}]_{D}K^{±} decays ﻿

(American Physical Society (APS), 2011)
We present a study of the decays B±→DK± with D mesons reconstructed in the K+π−π0 or K−π+π0 final states, where D indicates a D0 or a D⎯⎯⎯0 meson. Using a sample of 474×106 BB⎯⎯⎯ pairs collected with the BABAR detector at ...
• #### Search for Production of Invisible Final States in Single-Photon Decays of $Υ(1S)$ ﻿

(American Physical Society (APS), 2011)
We search for single-photon decays of the $Υ(1S)$ resonance, $Υ→γ+$ invisible, where the invisible state is either a particle of definite mass, such as a light Higgs boson $A^0$, or a pair of dark matter particles, ...
• #### Studies of $τ^{-}→ηK^{-}ν_{τ}$ and $τ^{-}→ηπ^{-}ν_{τ}$ at BABAR and a Search for a Second-Class Current ﻿

(American Physical Society (APS), 2011)
We report on analyses of tau lepton decays $τ^{−}→ηK^{−}ν_{τ}$ and $τ^{−}→ηπ^{−}ν_{τ}$, with $η→π^{+}π^{−}π^{0}$, using $470 fb^{−1}$ of data from the BABAR experiment at PEP-II, collected at center-of-mass energies ...
• #### Study of $B→πlν$ and $B→ρlν$ Decays and Determination of $|V_{ub}|$ ﻿

(American Physical Society (APS), 2011)
We present an analysis of exclusive charmless semileptonic B-meson decays based on $377×10^{6} B\overline{B}$ pairs recorded with the BABAR detector at the $Υ(4S)$ resonance. We select four event samples corresponding ...
