We report a measurement of the CP violation parameters in b->c anti-c d decays. Mixing-induced CP violation involving this transition is studied using a sample of B0->J/psi pi0, D*+D*- and D*+-D-+ decays with a data set accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. CP violation parameters are extracted from a fit to the distributions of time intervals between two B0 meson decay vertexes.
The $CP$ violation observables $S$ and $C$ in the decay channel $B^0 !rightarrow D^+ D^-$ are determined from a sample of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, collected by the LHCb experiment and corresponding to an int
I report recent measurements in b-hadron decays reconstructed in the full data set of sqrt{s} = 1.96 TeV proton-antiproton collisions collected by the CDF experiment at the Tevatron. These include the final CDF results on: measurements of CP asymmetr
The decay-time-dependent $CP$ asymmetry in $B^0 to D^{*pm}D^{mp}$ decays is measured using a data set corresponding to an integrated luminosity of $9$fb$^{-1}$ recorded by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7,
We present a summary of recent studies on $CP$ violation with the Belle experiment using the final data sample of $772 times 10^{6}$ Bbar{B} pairs produced at the Ypsilon(4S) resonance at the KEK asymmetric e^+ e^- collider. We discuss preliminary me
The BaBar detector and SLAC PEP-II asymmetric e+e- collider tuned to the Y(4s) resonance has collected around 23M B0 anti-B0 pairs in year 2000. The total data sample for run 1 is 20.7fb-1, using this data we present the study of sin2beta, with sampl
