Measurement of the double Dalitz decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
The BESIII experiment measured the rare decay of the eta meson into two electron-positron pairs, determining its branching fraction to be about 2.6 × 10⁻⁵.
Observation of Polarization and Determination of Its Electric and Magnetic Moments in
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
The BESIII experiment observed the polarization of the hyperon Ξ(1530)^0 in ψ(3686)→Ξ(1530)^0 anti‑Ξ(1530)^0 decays and measured its electric and magnetic multipole moments via ang…
Search for the isospin-violating decays and
BESIII Collaboration, M. Ablikim, M. N. Achasov +701
Using a sample of ~ events collected with the BESIII detector, we perform a search for the isospin-violating decays $Ï_{cJ}\toÎ\barΣ^{0}+c…
Precise Measurement of Matter-Antimatter Asymmetry with Entangled Hyperon Antihyperon Pairs
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
A search for violation with an entangled system of pairs is performed, using events collected with the BESIII experiment. A n…
