Semileptonic Decay of $B_c$ to ${\eta }_c$ and $J/\psi$ on the Light Front

Shuo Tang, Shaoyang Jia, Pieter Maris +1

We study the semileptonic decay of the $B_c(0^{-})$ to charmonia through the bottom-to-charm-quark electroweak current in the framework of basis light-front quantization. Explicitly…
