Evidence for $D^0\bar{D}^0$ Mixing
We present evidence for D0-anti-D0 mixing in D0 --> K+pi- decays from 384 fb^{-1} of e+e- colliding-beam data recorded near sqrt(s) 10.6 GeV with the BaBar detector at the PEP-II storage rings at SLAC. We find the mixing parameters x'^2 = [-0.22 +- 0.30 (stat.) +- 0.21 (syst.)] x 10^{-3} and...

| description | We present evidence for D0-anti-D0 mixing in D0 --> K+pi- decays from 384 fb^{-1} of e+e- colliding-beam data recorded near sqrt(s) 10.6 GeV with the BaBar detector at the PEP-II storage rings at SLAC. We find the mixing parameters x'^2 = [-0.22 +- 0.30 (stat.) +- 0.21 (syst.)] x 10^{-3} and y' = [9.7 +- 4.4 (stat.) +- 3.1 (syst.)] x 10^{-3}, and a correlation between them of -0.94. This result is inconsistent with the no-mixing hypothesis with a significance of 3.9 standard deviations. We measure R_D, the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates, to be [0.303 +- 0.016 (stat.) +- 0.010 (syst.)]%. We find no evidence for \CP violation. |

We find the mixing parameters x'^2 = [-0.22 +- 0.30 (stat.) +- 0.21 (syst.)] x 10^{-3} and y' = [9.7 +- 4.4 (stat.) +- 3.1 (syst.)] x 10^{-3}, and a correlation between them of -0.94. This result is inconsistent with the no-mixing hypothesis with a significance of 3.9 standard deviations. We measure R_D, the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates, to be [0.303 +- 0.016 (stat.) +- 0.010 (syst.)]%. We find no evidence for \CP violation.</abstract><pub>American Physical Society</pub><doi>10.1103/PhysRevLett.98.211802</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> |
