Distinguishing Low-lying Vector Beauty-charm Meson via Polarization Analysis

Yiqi Geng, Mingqi Cao, Ruilin Zhu

To distinguish the low-lying vector beauty-charm meson, we systematically study the $B_c^{\ast }\to B_c+\gamma$, $B_c^{\ast }\to \ell +{\nu }_{\ell }$ and $B_c^{(\ast )}\to J/\psi +nh$ processes within effective…
