BESIII Observes Polarization of Baryons in J/ψ Decay The BESIII collaboration observed baryon polarization in baryon-antibaryon (matter-antimatter particle) events from J/ψ particles produced at the BEPCII collider. The paper was published in Nature Physics on May 6.
Precision measurement of Ds+→μ+ν at BESIII The Beijing Spectrometer Experiment (BESIII) has recently reported the world’s best measurement of the leptonic decay Ds+→μ+ν by analyzing the data sample taken at the center-of-mass energy of 4.178 GeV during 2016.
BESIII Accumulates 10 Billion J/ψ Events The BESIII detector finished accumulating a sample of 10 billion J/ψ events together with a continuum data sample on Feb. 11. The 10 billion J/ψ-event sample accumulated at BESIII is the world's largest data sample produced directly from electron-positron annihilations.
