We report the results of a CP violation analysis of the decay B{sup {+-}} {yields} D{sub {pi}{sup +}{pi}{sup -}{pi}{sup 0}}K{sup {+-}}, where D{sub {pi}{sup +}{pi}{sup -}{pi}{sup 0}} indicates a neutral D meson detected in the final state {pi}{sup +}{pi}{sup -}{pi}{sup 0}, excluding …

We study e(+)e(-)-> J/psi c ($) over bar by measuring the invariant mass distribution recoiling against fully reconstructed J/psi decays, using 124 fb(-1) of data collected at a center-of-mass energy of 10.6 GeV with the BABAR detector. We observe signals for eta(c)(1S), …

We describe a measurement of the direct CP asymmetry between inclusive b-->sgamma and (b) over bar -->(s) over bar gamma decays. This asymmetry is expected to be less than 0.01 in the standard model, but could be enhanced up to about 0.10 …
