Observation of J/ψ Electromagnetic Dalitz Decays to X(1835), X(2120) and X(2370)
BESIII recently reports the first observation of J/ψ Electromagnetic (EM) Dalitz decays to X(1835), X(2120) and X(2370) and the measurement of the transition form factor of J/ψ to X(1835). It has...

The most precise measurements of the Lambda Decay Parameter
The BESIII collaboration has presented the most precise measurements of CP asymmetry and decay parameters with entangled Λ-Λbar pairs. The results are published in the journal Physical Review Let...

First observation of the direct production of a non-vector state in e+e- annihilation
The BESIII Collaboration has observed the direct production of an axial vector particle, χc1(1P), in electron-positron (e+e-) annihilation. The paper has been published in Physical Review Letters...

First evidence for the first neutral open-strange hidden-charm tetraquark state
The BESIII Collaboration recently reported the evidence of a new exotic multi-quark state, namely Zcs(3985)0. It is the neutral partner of the charged tetraquark Zcs(3985)+ observed in 2021 at BES...
