HFAG-charm averages
Marco Gersabeck (for the HFAG-charm group)
TL;DR
This paper reviews the latest combined measurements of charm mixing and CP violation parameters, highlighting current uncertainties and the compatibility of CP asymmetries with zero, to improve understanding of charm meson behavior.
Contribution
It provides updated averages of charm mixing and CP violation parameters and discusses the impact of individual measurements on these averages.
Findings
CP-even eigenstate is shorter lived
Oscillation frequency of charm mesons remains uncertain
All CP asymmetries are consistent with zero within less than 3 sigma
Abstract
The extraction of charm mixing and CP violation parameters requires the combination of many measurements. The latest averages are reviewed and the contribution of individual measurements is discussed. While it is established that the CP-even eigenstate is the shorter lived, the oscillation frequency of charm mesons is still not known to high accuracy. All CP asymmetries are found to be compatible with zero within less than 3 sigma.
