Search for the charged lepton flavour violating decay $η^{'} \to e μ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Based on $(8998 \pm 40) \times 1 0^{6}$ $J / ψ$ events collected in $e^{+} e^{-}$ collisions at $s = 3.097$ GeV with the BESIII detector, we present a search for the charged lepton flavou…

Proof of principle for nucleon polarization measurement at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +754

A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using $10.09 \times 1 0^{9}$ $J / I ¨ $ events at BESIII, the…

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.
