Recent Results From BaBar

Recent results on searches of new physics using data recorded by the BaBar detector at the SLAC PEPII asymmetric-energy e⁺e^- storage ring at a center-of-mass energy near 10.58 GeV are presented.

These results include observation of a new particle Y (4260) with hidden charm content and probable quantum numbers J^PC = 1^{- -}decaying into p⁺ p^- J/y final state in events where large energy is carried away by initial state photon radiation. Searches for other decay modes, which might relate to production and decay of Y (4260) are discussed. Also are presented results from observation of the recently discovered X (3872) with unknown quantum numbers in B ® X K decays, and measurement of branching fraction of this new state into final state containing J/y. Also are presented recent updates on measurements of CP asymmetry from b-s penguin decays and world's best limits on lepton flavor violation in tau decays. Non-trivial tests of SUSY combining the observed CP asymmetry in decays and improved upper limit on Branching Ratio of t®mg, are also discussed.
