Review on D0 - Anti-D0 Mixing

We review the current status of D{sup 0}-{anti D}{sup 0} mixing, with special emphasis in the most recent results. We begin with a discussion of charm mixing and CP violation phenomenology, the evolution with the decay proper time, and physics processes contributing to these. Then we follow with the summary of the main experimental techniques and the results in the various final states. We make use of the analysis reporting the first evidence of D{sup 0}-{anti D}{sup 0} mixing by BaBar in D{sup 0} {yields} K{sup +}{pi}{sup -} decays as a textbook example, and then we discuss the results from other two-body and three-body final states. We conclude with the combination of all experimental results. Time-integrated CP violation measurements are not discussed here.
