چکیده
We present a measurement of the standard model CP violation parameter sin2 phi(1) based on a 29.1 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson is fully reconstructed as a J/psi K(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psi K(L), or J/psi K(*0) decay and the flavor of the accompanying B meson is identified from its decay products. From the asymmetry in the distribution of the time intervals between the two B meson decay points, we determine sin2 phi(1) = 0.99+/-0.14(stat)+/-0.06(syst). We conclude that we have observed CP violation in the neutral B meson system.

We present a measurement of the Standard Model CP violation parameter sin 2φ1 based on a 29.1 fb −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. One neutral B meson is fully reconstructed as a J/ψKS , ψ(2S)KS , χc1KS , ηcKS , J/ψKL or J/ψK ∗0 decay and the flavor of the accompanying B meson is identified from its decay product...
متن کامل– 1 – PRODUCTION AND DECAY OF b - FLAVORED HADRONS
The b quark belongs to the third generation of quarks and is the weak–doublet partner of the t quark. The existence of the third–generation quark doublet was proposed in 1973 by Kobayashi and Maskawa [1] in their model of the quark mixing matrix (“CKM” matrix), and confirmed four years later by the first observation of a bb meson [2]. In the KM model, CP violation is explained within the Standa...
متن کاملDetermining the Neutral D Mixing Parameters
Evidence for mixing in the neutral D meson system has recently been reported. Assuming negligible CP violation, non-vanishing width and mass differences between the two neutral D mass eigenstates has been found. Theoretical predictions of these are rather difficult, obscuring detection of New Physics contributions. However, the observation of CP violation in the D system would be a good signal ...
متن کاملSLAC-PUB-11888 Rare hadronic B decays.
The study of rare hadronic B-meson decays with branching fractions O(10) enable us to probe a wide range of phenomena. Such decays can be used to probe our understanding of the CKM [1] description of quark mixing and CP violation (CPV ) in the Standard Model of Particle Physics (SM) by measuring all three of the Unitarity Triangle angles α, β and γ, as well as charge asymmetries in direct CPV ∆...

متن کاملCP Violation and Heavy Hadrons
I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay Λ → pπ, (ii) Charm: indirect CP violation in the D system, both within and beyond the SM, and (iii) Beauty: indirect CP violation in the neutral B-meson system beyond the SM.
