Observation of in
BESIII Collaboration
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state with a significance of . The mass…
Search for and improved measurement of the branching fraction for
BESIII Collaboration, M. Ablikim, M. N. Achasov +412
Using fb of electron-positron annihilation data collected at ~GeV with the BESIII detector, we report the results of a search for the flavor-changin…
Observation of the electromagnetic doubly OZI-suppressed decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +411
Using a sample of billion events accumulated with the BESIII detector at the BEPCII collider, we report the observation of the decay , which is…
Measurement of the proton form factor by studying
M. Ablikim, M. N. Achasov, X. C. Ai +409
Using data samples collected with the BESIII detector at the BEPCII collider, we measure the Born cross section of at 12 center-of-mass energies fr…
Observation and Spin-Parity Determination of the in
M. Ablikim, M. N. Achasov, X. C. Ai +413
We report an observation of the process at low mass with a statistical significance larger than 12.9 using a data…
An amplitude analysis of the system produced in radiative decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +417
An amplitude analysis of the system produced in radiative decays is presented. In particular, a piecewise function that describes the dynamics of the $π^{0}π^{0}…
