Excluding Local Hidden Variables in $I^ I^ˉ $ Production: The Incompatibility with Angular-Momentum Conservation and CPT Invariance

Junle Pei, Lina Wu, Tianjun Li +1

We analyze spin entanglement in $I^ I^ˉ $ pairs produced in the decays of spin-zero particles, contrasting predictions from quantum field theory (QFT) with those of local hidden-v…

Bypassing Spin-Analyzing Power Dependence for Quantum Entanglement at Colliders: A Case Study of $I^ I^ˉ $

Junle Pei, Tianjun Li, Lina Wu +2

We study, as a concrete case study using the $I^ (\to p I ¨ ^{-}) I^ˉ (\to p ˉ I ¨ ^{+})$ system, whether quantum entanglement in fermion pairs produced at colliders can be certified sol…

Determining the Spin Density Matrix via Its Rank and Probing the Quantum Entanglement and Bell Non-Locality at the Lepton Colliders

Liwei Liu, Xiqing Hao, Dianwei Wang +2

Considering two-fermion $F_{a} F_{b}$ productions and decays via one scalar or photon exchange at the $e^{+} e^{-}$ collider, we show that the rank $r_{I ¨} $ of spin density matrix $I ¨ $ is equ…

Determining the Spin-Analyzing Powers via Invariants of the Spin Correlation Matrices and Probing the Bell Non-Locality at the Lepton Colliders

Dianwei Wang, Xiqing Hao, Liwei Liu +2

We consider the two-fermion $F_{a} F_{b}$ productions and decays via one mediator exchange at the $e^{+} e^{-}$ collider. With the assumption that the spin is defined via the Lorentz symmet…

Study of $I ¨ \to K K ˉ$ in the amplitude analysis of $D^{+} \to K_{S}^{0} K_{L}^{0} I ¨ ^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +772

We present the first amplitude analysis and branching fraction measurement of $D^{+} \to K_{S}^{0} K_{L}^{0} I ¨ ^{+}$ decay. The analysis uses a dataset corresponding to an in…
