Determination of the pseudoscalar decay constant via
BESIII Collaboration, M. Ablikim, M. N. Achasov +452
Using a data sample collected at an center-of-mass energy of GeV with the BESIII detector, we measure the branching fraction of…
Observation of and Improved Measurements of
M. Ablikim, M. N. Achasov, S. Ahmed +458
Using a data sample corresponding to an integrated luminosity of 2.93~fb recorded by the BESIII detector at a center-of-mass energy of GeV, we present an analysis of…
