Measurement of D0–D‾0 mixing and search for CP violation in D0 → K+K−,π+π− decays with the full Belle data setStarič, Marko (Avtor) Biswal, Jyoti Prakash (Avtor) Bračko, Marko (Avtor) Golob, Boštjan (Avtor) Korpar, Samo (Avtor) Križan, Peter (Avtor) Nanut, Tara (Avtor) Pestotnik, Rok (Avtor) Petrič, Marko (Avtor) Ribežl, Eva (Avtor) Stanič, Samo (Avtor) Zupanc, Anže (Avtor) charm mesonsmixingCP violationWe report an improved measurement of $D^0–{\overline{D}}^0$ mixing and a search for $CP$ violation in $D^0$ decays to $CP$ -even final states $K^+K^−$ and $\pi^+\pi^-$. The measurement is based on the final Belle data sample of $976 fb^{−1}$. The results are $y_CP=(1.11±0.22±0.09)%$ and $A_Γ=(−0.03±0.20±0.07)%$, where the first uncertainty is statistical and the second is systematic.20162017-07-17 08:26:32Znanstveno delo66891ISSN: 0370-2693UDK: 539.1OceCobissID: 6500101COBISS_ID: 29823783DOI: 10.1016/j.physletb.2015.12.025ISSN pri članku: 0370-2693NUK URN: URN:SI:UM:DK:FRSJPXHTsl
