Özet

By analyzing a data sample of 2.93 fb-1 collected at s=3.773 GeV with the BESIII detector operated at the BEPCII storage rings, we measure the branching fractions B(D0→ωη)=(2.15±0.17stat±0.15sys)×10-3, B(D0→ηπ0)=(0.58±0.05stat±0.05sys)×10-3, B(D0→η′π0)=(0.93±0.11stat±0.09sys)×10-3, B(D0→ηη)=(2.20±0.07stat±0.06sys)×10-3 and B(D0→η′η)=(0.94±0.25stat±0.11sys)×10-3. We note that B(D0→ωη) is measured for the first time and that B(D0→ηη) is measured with much improved precision.
