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.

Precise Measurement of Matter-Antimatter Asymmetry with Entangled Hyperon Antihyperon Pairs

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

A search for $C P$ violation with an entangled system of $I^^{-} I^ˉ ^{+}$ pairs is performed, using $(10, 087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII experiment. A n…

Spin density matrix of baryon-antibaryon pairs in electron-positron annihilation with $P$ and $C P$ violation including electron mass

Chun-Qiu Zhao, Xu Cao, Jian-Ping Dai

In the center-of-mass frame, the spin density matrix for octet baryon-antibaryon pairs produced in polarized electron-positron annihilation is unambiguously determined within the o…

Creating true muonium via charmonium radiative decay

Jian-Ping Dai, Hai-Bo Li, Shuai Zhao +1

True muonium, the bound state of a muon and an antimuon ( $I^¼^{+} I^¼^{-}$ ), has long been theoretically predicted but remains experimentally elusive. We investigate the production of tru…
