Light, heavy light, and asymmetry

Liang Han (U.S.T.C., Hefei, China), Chen Wang and Yifan Xiang (undergraduates at U.S.T.C.) and Siqi Yang (U.S.T.C. and now at U. of Iowa) are the primary analysts for this measurement.

DZero has used an asymmetry in dimuon events to measure the weak-force mixing angle sin2θW.

DZero measured the difference in the rates of the decays B → μ ν D0 vs. B+ → μ+ ν D0.

Antimatter and interference

The DZero collaboration has measured the difference (called the asymmetry) between the rate of a specifi decay for the D+ and the D- mesons.
