Abstract:	摘要： We observe $D^0-\bar{D}^0$ mixing in the decay $D^0\rightarrow K^+ ^-$ using a data sample of integrated luminosity 976 fb$^{-1}$ collected with the Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. We measure the mixing parameters ${x'}^2 = (0.09\pm0.22)\times 10^{-3}$ and $y' = (4.6\pm3.4)\times 10^{-3}$ and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates $R_D = (3.53\pm0.13)\times 10^{-3}$, where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level. 6 pages, 4 figures 出版者： American Physical Society (APS) 出版日期： 2014-03-17 出處： Physical Review Letters, 2014-03, Vol.112 資源來源： American Physical Society Publications 識別號： ISSN: 0031-9007 識別號： EISSN: 1079-7114 識別號： DOI: 10.48550/arxiv.1401.3402 識別號： DOI: 10.1103/physrevlett.112.111801
