Polarization and quantum entanglement effects in $B_c^{\pm }\to J/\psi +{\pi }^{\pm }+{\pi }^0$ process

Kaiwen Chen, Yiqi Geng, Yichao Jin +2

Motivated by the very recent observation of the $B_c^{+}\to J/\psi +{\pi }^{+}+{\pi }^0$ decay using proton-proton collision data by the LHCb collaboration, we study the four-body angular distribut…
