Precision measurement of CP violation and branching fractions in decays and search for the rare decay
R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta +1177
The decay , with a asymmetry expected to be close to zero in the Standard Model, is theoretically clean and sensitive to potential new ph…

Observation of a threshold enhancement in the spectrum in decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +677
Based on the events collected with the BESIII detector, we present a high-precision study of the mass spectrum in $ψ(3686)\rightar…
