Measurement of cross sections at 2.000 to 3.080 GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +610
The Born cross sections for the process are measured at 22 center-of-mass energies from 2.000 to 3.080 GeV using data collected with the BESIII detector…

Search for di-photon decays of an axion-like particle in radiative decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +614
We search for the di-photon decay of a light pseudoscalar axion-like particle, , in radiative decays, using 10 billion events collected with the BESIII detector. We…
