Quantum Entanglement Autodistillation in Baryon Pair Decays

Hai-Long Feng, Hao Tang, Wu-zhong Guo +1

We study the spin-entangled mixed state of a spin-1/2 baryon-antibaryon pair produced in the process e+e- to J/psi, psi(2S) to BBbar. We demonstrate that the spin entanglement of t…

CP violation analysis of $D^{0} \to M^{0} K \to M^{0} (I ¨ ^{\pm} ℓ^{\mp} I^½)$

Wen-Jie Song, Shi-Qi Wang, Qin Qin +1

CP violation in the charm sector is highly sensitive to new physics due to its small predicted value within the standard model. By this work, we investigated the CP violation in th…

Double-mixing CP violation in $B$ decays

Wen-Jie Song, Yin-Fa Shen, Qin Qin

We study a long-overlooked CP violation observable, termed double-mixing CP violation, which arises from the interference between two neutral meson oscillating paths involved in a…
