CP Violation

oral

We present a new analysis that measures CP-violating asymmetries in D*-tagged D^0-->pi^+pi^- decays, where any enhancement from the standard model prediction (of the order of 10^-3) would be unambiguous evidence for New Physics. A technique combining asymmetries of pi^+pi^-, and K^-pi^+ D^0 decays highly suppresses systematic uncertainties due to detector charge-asymmetric efficiencies...

CP Violation

The CDF experiment at the Tevatron collider presents improved bounds on the CP-violating phase beta_s and on the decay-width difference DeltaGamma_s of the neutral B_s^0 meson system. We use 6500 B_s^0 --> J/psi Phi decays collected by the dimuon trigger and reconstructed in a sample corresponding to 5.2 fb^{-1} of data. Besides exploiting a two-fold increase in statistics with respect to...

CP Violation

LHCb is an experiment optimised to search for New Physics through measurements of the decays of B and D hadrons, in particular those which allow access to CP-violating observables. The principal goals are studies of B_s mixing-induced CP-violation in channels such as B_s->J\psi \phi, a precise measurement of the unitary triangle angle \gamma, and the search for CP-violation in the...
