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.

Measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +416

We perform a measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays using a dataset of approximately $772 \times 1 0^{6}$ and $521 \times 10…
