BESIII Sets New Bound for Sub-GeV Dark Matter Interactions
The BESIII Collaboration recently reports the search for sub-GeV dark particles in η→π⁰+invisible decay and provides a new bound for the sub-GeV dark matter, which has been published in Physica...

BESIII Reports First Measurements of Antineutron–Proton Annihilation into Multi-Pion Final States
Recently, the BESIII collaboration has reported new results on antineutron–proton interactions by measuring the annihilation processes n̄ p → 2 π+ π-, n̄ p → 2 π+ π- π0, and n̄ p → 2 π...

BESIII Observes Polarization and Measures Electric and Magnetic Moments of the Ξ(1530)⁰ Baryon for the First Time
The BESIII Collaboration has achieved a major advance in the study of baryon structure by observing the polarization of the spin-3/2 hyperon Ξ(1530)⁰ and determining its electric and magnetic mom...
