Abstract

We review results from FNAL E791 concerning D0-D0bar mixing and CP violation in D meson decays. We have searched for mixing in semileptonic D0 -> K+\ell-\bar{\nu} decays and in hadronic D0 -> K+\pi- and D0 -> K+\pi-\pi+\pi- decays. We have searched for CP violation in D0 -> K+K- / \pi+\pi- and D+ -> \phi\pi+ / \bar{K}^{*0}K+ / K+K-\pi+ / \pi+\pi-\pi+ decays. Finally, we have measured the difference in decay widths \Delta\Gamma between the two mass-eigenstates of the D0-D0bar system. This parameter affects the rate of D0-D0bar mixing. We combine our results with those from other experiments to obtain confidence intervals incorporating all published experimental data.
