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…

From topological amplitudes to rescattering dynamics in charmed baryon decays

Ying-Xin Lai, Di Wang

Charmed baryon decays play an important role in studying the weak and strong interactions, which have been studied in the rescattering dynamics and topological diagram approach. In…

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…

$U$ -spin sum rules for two-body decays of bottom baryons

Si-Jia Wen, Wei-Chen Fu, Di Wang

$U$ -spin symmetry, which reflects the symmetry between the down-type $d$ and $s$ quarks, is a powerful tool for analyzing heavy hadron weak decays. Motivated by recent experimental…

Unveiling a Universal Formalism for Quantum Entanglement in Arbitrary Spin Decays

Junle Pei, Lina Wu, Dianwei Wang +2

We present a comprehensive theoretical framework for probing quantum entanglement in the decay angular distributions of a spin- $S$ particle-antiparticle pair $A A ˉ$ , where each…

$C P$ asymmetries in the $I^_{c}^{+} \to p K_{S}^{0}$ and $I^_{c}^{+} \to I^£^{+} K_{S}^{0}$ decays

Di Wang, Si-Jia Wen

$C P$ asymmetry is a crucial element in interpreting the matter-antimatter asymmetry in the universe and searching for new physics beyond the Standard Model. In this work, we study…
