Search 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 کامل\μμ decay in the MSSM
We present the results of the complete one-loop computation of the Bd ,s 0 →ll decay rate in the MSSM. Both sources of the FCNC, the CKM matrix and off-diagonal entries of the sfermion mass matrices are considered. Strong enhancement of the branching ratio ~compared to the SM prediction! can be obtained in the large tan b;m t /mb regime in which the neutral Higgs boson ‘‘penguin’’ diagrams domi...
متن کاملSearch 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 کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولSearch 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...
