Contribution

It summarizes recent experimental findings on $D^0$ mixing and CP violation, emphasizing the importance of future measurements for discovering new physics.

Findings

$D^0$ mixing is experimentally established.

No CP violation in charm sector has been observed.

Future experiments could reveal CP violation indicating new physics.

Abstract

We review basic phenomenology on $D^0$ mixing/CP violation and recent experimental results on them. $D^0$ mixing is established by combining results from multiple experiments but no CP violation in the charm sector has been seen. $D^0$ mixing from a single experiment will clarify the size of the mixing, and observation of CP violation in charm decays at the present level of experimental sensitivity would be clear signal of new physics beyond the standard model.
