B Decays and CP Violation from BABAR
We present some recent BABAR measurements of the magnitudes of the elements Vub and Vcb of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix, and of the angles α and γ of the unitary triangle of the standard model of the electroweak interactions. Most of the measurements presented here are based on the full BABAR Υ(4S) dataset, consisting of about 467 × 106 BB pairs. Invited talk presented at t...
متن کاملStudies of CP Violation at BABAR
BABAR has studied the time dependent asymmetries in the the decays B → J/ψK S and B → ψ(2S)K S in a data set of 9.0 fb taken at the Υ (4S) resonance. In these channels we reconstruct 168 events of which 120 are flavor tagged and used in a likelihood fit where we determine sin 2β. The flavor of the other neutral B mesons is tagged using information primarily from identified leptons and Kaons. A ...
متن کاملBeyond CP violation: hadronic physics at BaBar
I report on recent studies of hadronic physics performed by the BaBar Collaboration. Emphasis is given to the measurement of the properties of newly discovered charmed hadrons and to the searches for light and heavy pentaquarks. Contributed to the Proceedings of the First APS Topical Group Meeting on Hadron Physics Fermilab, Batavia, IL (October 24-26, 2004). Stanford Linear Accelerator Center,...
متن کاملFirst CP Violation Results from BABAR
We present a preliminary measurement of time-dependent CP -violating asymmetries in B0 → J/ψK0 S and B0 → ψ(2S)K0 S decays recorded by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The data sample consists of 9.0 fb collected at the Υ (4S) resonance and 0.8 fb off-resonance. One of the neutral B mesons, produced in pairs at the Υ (4S), is fully reconstructed. The flavor of the ...
متن کاملSelected Topics in CP Violation and Weak Decays from BABAR
CP violation has been established in the Bmeson system [1] [2] and B-factories are now focusing their attention on over-constraining the angles and sides of the Unitarity Triangle, which is a partial representation of the CabibboKobayashi-Maskawa (CKM) matrix [3]. The study of charmless B decays allows us to make such measurements and also to probe physics beyond the Standard Model (SM). In thi...
