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.

Observation of the charmless purely baryonic decay $Λ_{b}^{0} \to Λ p p$

LHCb collaboration, R. Aaij, M. Abdelfatah +1117

A search for the charmless purely baryonic decay $Λ_{b}^{0} \to Λ p p$ is performed using proton-proton collision data recorded by the LHCb experi…
