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.

Precision Studies and Searches for CP Asymmetries in the Inclusive Decay $I^_{c}^{+} \to I^ X$

BESIII Collaboration, M. Ablikim, M. N. Achasov +716

Based on $e^{+} e^{-}$ annihilation data collected with the BESIII detector at center-of-mass energies from 4.600 to 4.699 GeV, corresponding to an integrated luminosity of 4.5 fb$^{-1}…
