Search for D0−D0 Mixing
We report on a search for D0−D0 mixing made by a study of the ‘wrong-sign’ process D →K+π−. The data come from an integrated luminosity of ee collisions at √ s ≈ 10GeV consisting of 9.0 fb, recorded with the CLEO-II.V detector. We measure the time-integrated rate of the ‘wrong-sign’ process D → Kπ, relative to that of the Cabibbo-favored process D →K+π−, to be Rws = (0.34 ± 0.07 ± 0.06)%. We st...
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 techniparticles in e+jets events at D0.
We search for the technicolor process pp-->rhoT/omegaT-->WpiT in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb(-1), recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions pi(T) decay dominantly into bb, bc, or bc, depending on their charge. In these events b and c quarks are identified by their sec...
متن کاملSearch for D0–D0 Mixing and Rare Charm Decays
Based on a dataset acquired by the BABAR experiment running on and near the Υ (4S) resonance from 1999-2002, an upper limit is set on the rate of D0–D0 mixing using the decay mode D∗+ → D0π+, followed by a semi-leptonic decay of the D0. Results are compared to previous BABAR analysis using hadronic decays. We also set limits on the flavor-changing neutral current decays D0 → e+e− (μ+μ−) and the...
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
