Direct CP Violation in B → π+π−π Determination of α without discrete ambiguity
Direct CP violation in the hadronic decays B̄0 → π+π−π0 is investigated near the peak of the ρ0 taking into account the effect of ρ−ω mixing. Branching ratios for processes B±,0 → ρ±,0π±,0 and B → ωπ are calculated as well. We find that the CP violating asymmetry is strongly dependent on the CKM matrix elements. For a fixed N eff c , the CP violating asymmetry, aCP , has a maximum of order −40% ...

متن کاملMeasurement of partial widths and search for direct CP violation in D0 meson decays to K-K+ and pi-pi+.
We present a measurement of relative partial widths and decay rate CP asymmetries in K-K+ and pi(-)pi(+) decays of D0 mesons produced in pp collisions at sqrt[s]=1.96 TeV. We use a sample of 2x10(5) D(*+)-->D0pi(+) (and charge conjugate) decays with the D0 decaying to K-pi(+), K-K+, and pi(-)pi(+), corresponding to 123 pb(-1) of data collected by the Collider Detector at Fermilab II experiment ...
