Measurement of the double Dalitz decay $I^\cdot \to e^{+} e^{-} e^{+} e^{-}$

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.

Multi-channel joint analysis of the exotic charmonium-like state $T_{c c ˉ} (4020)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

This paper reports the first multi-channel joint analysis to identify the properties of the exotic charmonium-like state $T_{c c ˉ} (4020)$ via the electron-positron annihilation…
