Measurements of indirect CP asymmetries in D0 → K- K+ and D0 → π- π+ decays.
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 ...
متن کاملMeasurement of Cp Asymmetries at Belle
The Belle experiment at the KEK B factory has collected 93 fb of electron positron collisions at √ s = 10.6 GeV. This has produced a sample of 85 million BB̄ meson pairs that can be used to study CP violation in rare (and not so rare) B decay modes. Here I report on a measurement of indirect CP violation in the decay B → J/ψK S, as well as time dependent CP asymmetries in rarer modes such as B →...
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...
متن کاملSearch for CP violation in D0 decay.
Using data taken with the CLEO II detector, we have searched for evidence of CP violation in the charm system. We look for asymmetries in the number of decays of D 0 's and
متن کاملTime-dependent CP asymmetries in Bs decays at LHCb
The LHCb experiment will search for New Physics in Bs mixing. The Bs mixing phase will be extracted from the measurement of the time-dependent CP asymmetry in exclusive Bs decays governed by the b → cc̄s quark-level transition. Large New Physics effects can be discovered or excluded with the data collected during the very first physics run of LHC. Based on Monte Carlo simulations of the LHCb det...
