Results of experiment Focus on direct CP violation with charm D mesons, D0 mixing and lifetime difference

A summary of some of the results of the experiment Focus, a high statistics charm photoproduction experiment performed at Fermilab, will be presented. Measurements will be shown of limits on the direct CP violation of the charmed D+ and D0 and on the mixing of the D0 meson (lifetime difference between the CP-even and CP-odd states of the D0 and 'wrong sign' decays).
