TL;DR
This paper reviews recent experimental results on charm meson mixing from BABAR, Belle, and CDF, indicating mixing occurs at about 1% and discussing searches for CP violation.
Contribution
It compiles and summarizes recent measurements of charm mixing and CP violation from multiple experiments using diverse methods.
Findings
Charm mixing is approximately 1%.
No significant evidence of indirect CP violation.
Multiple experimental approaches confirm mixing phenomena.
Abstract
A summary of the results of several recent studies of charm mixing is presented. A number of different methods were used, including the measurement of lifetime ratios for final states of different CP, time dependence of wrong-sign hadronic decays, fits to time-dependent Dalitz plots, and searches for wrong-sign semi-leptonic decays. Taken together, they suggest mixing is of order 1%. The status of searches for indirect CP violation is also reported.
