| dc.description | Measurement results on $D^0$-$\bar D^0$ mixing and CP violation are presented. FOCUS, a fixed target experiment at Fermilab, collected a high statistics photo-produced charm sample collected during the 96-97 run. We reconstructed more than 1 million charmed particles and compared the lifetimes of two $D^0$ meson decays to $K^-π^+$ and $K^-K^+$. The mixing parameter, $y_{\rm cp}$, we obtained is $(3.42\pm 1.39\pm 0.74)%$. We also searched CP asymmetries in $D^+\to K^-K^+π^+$, $D^0\to K^-K^+$ and $D^0\to π^-π^+$ decay modes. We did not see any evidence of CP violation by comparing the decay rates for particle and antiparticle. | |
