We present an update on total and partial branching fractions and on CP asymmetries in the semi-inclusive decay B -> Xs l+l-. Further, we summarize our results on branching fractions and CP asymmetries for semi-inclusive and fully-inclusive B -> Xs g
amma decays. We present the first result on the CP asymmetry difference of charged and neutral B -> Xs gamma$ decays yielding the first constraint on the ratio of Wilson coefficients Im (C8/C7).
New BABAR results on B mesons and quarkonia are presented: an analysis of B+ --> X(3872)K+ and B0 --> X(3872)K0 decays with X(3872) --> J/Psi pi+pi-, a precise measurement of the B mass difference Delta mB = m(B0) - m(B+) and a study of hadronic transition between Upsilon mesons.
In the past 10 years our knowledge of the parameters rho and eta of the Cabibbo-Kobayashi-Maskawa matrix has improved substantially. This article reviews the measurements that contributed to this advance, and discusses their implication in terms of u
nderstanding CP violation in the Standard Model and beyond.
We present a review of recent results from BaBar experiment. BaBar detector has collected about 256 millions of $Bbar B$ events at PEP-II, the asymmetric $e^+e^-$ collider located at SLAC running at the $Upsilon(4S)$ resonance. We have studied CP vio
lation in B mesons, observing the first evidence of direct CP violation in B meson decays and measured CP asymmetries relevant for the determination of the angles of the CKM Unitarity Triangle. BaBar physics program covers many other topics, including measurements of CKM matrix elements, charm physics, and search for new physics processes.
Results are presented on the study of three body decays of D0 -> K0s h+ h-, where h=pi/K and DS+ -> K0S K0S pi+. The data have been collected by the BaBar experiment at SLAC and are extracted from continuum e+ e- annihilations at the Upsilon(4S) energy.
