| $D^0$--$\bar{D}{}^0$ hadronic mixing and DCS decays from FOCUS (2005) | |||||||||
Abstract | |||||||||
| We present an analysis of the decay $D^0 \to K^+\pi^-$ from FOCUS. From a sample of 234 events we find a branching ratio of $\frac{\Gamma(D^0 \to K^+\pi^-)}{\Gamma(D^0 \to K^-\pi^+)} = (0.430^{+0.062}_{-0.061}\pm 0.031)%$ under the assumption of no mixing and no CP violation. We also present limits on charm mixing.. Comment: Proceedings from talk at 2004 DPF Meeting at University of California, Riverside | |||||||||
