Description
We study the spin-entangled mixed state of a spin-(\frac{1}{2}) baryon-antibaryon pair produced in the process (e^+e^-\to J/\psi,\psi' \to B\bar{B}). We show that the spin entanglement of the system can increase after the process that a baryon decays to a spin-(\frac{1}{2}) baryon and a spin-0 meson, an anti-baryon decays to a spin-(\frac{1}{2}) anti-baryon and a spin-0 meson.
