Short distance D-Dbar mixing
We review the status of Standard Model predictions for lifetimes and mixing rates of charmed mesons. It is shown that the short distance approach is able to reproduce tau(D^+)/tau(D^0) at leading order in the 1/m_c expansion. SU(3) violating effects from interactions with the soft hadronic backgroun...
