Time-dependent analysis of $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ decays and studies of the $K^{+} π^{-} π^{+}$ system in $B^{+} \to K^{+} π^{-} π^{+} γ$ decays

P. del Amo Sanchez, others

We measure the time-dependent $C P$ asymmetry in the radiative-penguin decay $B^{0} \to K_{S}^{0} π^{-} π^{+} γ$ , using a sample of $471$ million $Υ(4S) \to B{\kern 0.18em\overline{\kern…

Search for Long-Lived Particles in $e^{+} e^{-}$ Collisions

J. P. Lees, others

We present a search for a neutral, long-lived particle $L$ that is produced in $e^{+} e^{-}$ collisions and decays at a significant distance from the $e^{+} e^{-}$ interaction point into var…

Search for direct CP-violation in singly-Cabibbo suppressed D+- --> K+ K- pi+- decays

BaBar Collaboration, J. P. Lees, V. Poireau +359

We report on a search for direct CP asymmetry in the singly Cabibbo-suppressed decay D+- --> K+ K- pi+- using a data sample of 476 fb-1 accumulated with the BaBar detector running…

Search for Second-Class Currents in tau- -> omega pi- nu_tau

The BABAR Collaboration, B. Aubert

We report on an analysis of $τ^{-}$ decaying into $ω π^{-} ν_{τ}$ with $ω \to π^{+} π^{-} π^{0}$ using data containing nearly 320 million tau pairs collected with the BABAR detector at the PEP-II as…
