Beauty and charm results from B-factories
We present the proceedings of the lectures given at the 2008 Helmholtz International Summer School Heavy Quark Physics at the Bogoliubov Laboratory of Theoretical Physics in Dubna. In two lectures we present recent results from the existing B-factories experiments, Belle and BaBar. The discussed topics include short phenomenological motivation, experimental methods and results on B meson oscill...
متن کاملNEW RESULTS FROM THE B-FACTORIES BELLE and BABAR
Abstract. The BELLE detector has already accumulated e+e− collision data at the KEKB-collider corresponding to 600 f b−1. BaBar has accumulated data of approximately 390 f b−1 at PEP-II. Both are running on asymmetric energy e+e− colliders at the Υ(4S) energy. The paper selects important results from both experiments with the emphasis on CP violation in B meson decays and its implications for t...

متن کاملRadiative and Leptonic B-meson Decays from the B-factories
Radiative penguin decays of B-mesons, in which a b quark transitions to an s or d quark accompanied by either a photon or a pair of charged leptons (Fig. 1), are a sensitive probe of New Physics (NP) beyond the Standard Model (SM). These flavour changing neutral current decays are forbidden at tree level in the SM and hence strongly suppressed. In many NP scenarios these decays appear at the on...
متن کاملB-factories* - Ellio?t
(El a-ABSTRACT We briefly review the physics of CP violation and the interest of studying this phenomenon in the B-meson system. The need for very large numbers of B-decays is shown, and a number of approaches for B-factories are compared. In particular, e+e-linear and circular colliders are discussed in some detail, with specific examples presented .
