Search for $D^0-{\bar D}^0$ Mixing Using Doubly Flavor Tagged Semileptonic Decay Modes
We have searched for $D^0 - \bar{D}^0$ mixing in $D^{*+} \to \pi^+ D^0$ decays with $D^0 \to K^{(*)} e \nu$ in a sample of $e^+ e^- \to {c\bar c}$ events produced near 10.58 GeV. The charge of the slow pion from charged $D^*$ decay tags the charm flavor at production, and it is required to be consis...

| description | We have searched for $D^0 - \bar{D}^0$ mixing in $D^{*+} \to \pi^+ D^0$ decays with $D^0 \to K^{(*)} e \nu$ in a sample of $e^+ e^- \to {c\bar c}$ events produced near 10.58 GeV. The charge of the slow pion from charged $D^*$ decay tags the charm flavor at production, and it is required to be consistent with the flavor of a fully reconstructed second charm decay in the same event. We observe 3 mixed candidates compared to 2.85 background events expected from simulation. We ascribe a 50% systematic uncertainty to this expected background rate. We find a central value for the mixing rate of $0.4 \times 10^{-4}$. Using a frequentist method, we set corresponding 68% and 90% confidence intervals at $(-5.6, 7.4) \times 10^{-4}$ and $(-13, 12) \times 10^{-4}$, respectively. |

The charge of the slow pion from charged $D^*$ decay tags the charm flavor at production, and it is required to be consistent with the flavor of a fully reconstructed second charm decay in the same event. We observe 3 mixed candidates compared to 2.85 background events expected from simulation. We ascribe a 50% systematic uncertainty to this expected background rate. We find a central value for the mixing rate of $0.4 \times 10^{-4}$. Using a frequentist method, we set corresponding 68% and 90% confidence intervals at $(-5.6, 7.4) \times 10^{-4}$ and $(-13, 12) \times 10^{-4}$, respectively.</abstract><pub>American Physical Society</pub><doi>10.1103/PhysRevD.76.014018</doi><orcidid>https://orcid.org/0000-0003-0885-824X</orcidid><orcidid>https://orcid.org/0000-0003-4774-2194</orcidid><orcidid>https://orcid.org/0000-0001-6589-8673</orcidid><orcidid>https://orcid.org/0000-0003-4887-2150</orcidid><orcidid>https://orcid.org/0000-0003-3332-2615</orcidid><orcidid>https://orcid.org/0000-0003-2655-7643</orcidid><orcidid>https://orcid.org/0000-0002-3110-6022</orcidid><orcidid>https://orcid.org/0000-0002-9807-861X</orcidid><orcidid>https://orcid.org/0000-0001-5914-8614</orcidid><orcidid>https://orcid.org/0000-0002-8859-5453</orcidid><orcidid>https://orcid.org/0000-0003-2489-7812</orcidid><orcidid>https://orcid.org/0000-0002-9495-9145</orcidid><orcidid>https://orcid.org/0000-0003-4887-2150</orcidid><orcidid>https://orcid.org/0000-0002-8859-5453</orcidid></addata></record> |
