Contribution
It provides a comprehensive overview of the latest findings in charm meson mixing and CP violation, emphasizing their significance for new physics searches.
Findings
Mixing observed in D0 mesons for the first time.
CP violation effects are approaching detectable levels.
Results are consistent with Standard Model predictions, but leave room for new physics.
Abstract
The phenomenon of mixing in neutral meson systems has now been observed in all flavours, but only in the past year in the D0 system. The standard model anticipated that, for the charm sector, the mixing rate would be small, and also that CP violation, either in mixing or in direct decay, would be below the present levels of observability. It is hoped that further study of these phenomena might reveal signs of new physics. A review of recently available, experimental results is given.
