Study of $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events accumulated with the BESIII detector, we analyze the decays $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$ ( $l = e$ or $I^¼$ ) via the process…

Test of local realism via entangled $I^ I^ˉ $ system

BESIII Collaboration, M. Ablikim, M. N. Achasov +608

The non-locality of quantum correlations is a fundamental feature of quantum theory. The Bell inequality serves as a benchmark for distinguishing between predictions made by quantu…

Measurement of Branching Fractions for $I^_{c}^{+} \to n K_{S}^{0} I ¨ ^{+}$ and $I^_{c}^{+} \to n K_{S}^{0} K^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated at center-of-mass energies between $4.600 GeV$ and $4.699 GeV$ with the BESIII detector, we me…
