چکیده
A study of indirect CP violation in D0 mesons through the determination of the parameter AΓ is presented using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb(-1), collected with the LHCb detector and recorded at the center-of-mass energy of 7 TeV at the LHC. The parameter AΓ is the asymmetry of the effective lifetimes measured in decays of D0 and D0 mesons to the CP eigenstates K- K+ and π- π+. Fits to the data sample yield AΓ(KK)=(-0.35±0.62±0.12)×10(-3) and AΓ(ππ)=(0.33±1.06±0.14)×10(-3), where the first uncertainties are statistical and the second systematic. The results represent the world's best measurements of these quantities. They show no difference in AΓ between the two final states and no indication of CP violation.

Search for CP violation in D 0 and D + decays
A high statistics sample of photoproduced charm particles from the FOCUS (E831) experiment at Fermilab has been used to search for CP violation in the Cabibbo suppressed decay modes D+ → K−K+π+, D0 → K−K+ and D0 → π−π+. We have measured the following CP asymmetry parameters: ACP (K −K+π+) = +0.006± 0.011± 0.005, ACP (K −K+) = −0.001± 0.022± 0.015 and ACP (π −π+) = +0.048 ± 0.039 ± 0.025 where t...
متن کاملD0-D0 Mixing at BABAR
measure the rate of mixing with the observable yCP = (τKπ/τKK)− 1, where τKK and τKπ are respectively the mean lifetimes of CP-even D0 → K+K− and CP-mixed D0 → K−π+ decays. A new BABAR measurement of the mixing parameter yCP is presented for the first time in this conference. This new result is in good agreement with a previous BABAR measurement, obtained from a sample of D∗+ → D0π+ events, whe...

Using data collected by the FOCUS experiment at Fermilab, we report the discovery of the decay modes D0 → K−π+π+π+π−π− and D0 → π+π+π+π−π−π−. With a sample of 48 ± 10 reconstructed D0 → K−π+π+π+π−π− decays and 149 ± 17 reconstructed D0 → π+π+π+π−π−π− decays, we measure the following relative branching ratios: Γ(D0 → K−π+π+π+π−π−)/Γ(D0 → K−π+π+π−) = (2.70 ± 0.58± 0.38) × 10−3 Γ(D0 → π+π+π+π−π−π−...

where the first uncertainty is statistical and the second systematic. This represents a significant improvement in precision over the previous measurement of this parameter. Measurements of the parameter AΓ, defined as the CP asymmetry of the D0 effective lifetime when decaying to a CP eigenstate, are also presented. Using semi-leptonic b-hadron decays to tag the flavour of the D0 meson at prod...
متن کاملJ un 2 00 5 Search for T Violation in Charm Meson Decays
Using data from the FOCUS (E831) experiment, we have searched for T violation in charm meson decays using the four-body decay channels D0 → K−K+π−π+, D+ → K0 S K+π−π+, and D+ s → K 0 S K+π−π+. The T violation asymmetry is obtained using triple-product correlations and assuming the validity of the CPT theorem. We find the asymmetry values to be ATviol(D 0) = 0.010 ± 0.057(stat.) ± 0.037(syst.), ...
