\(B_c\rightarrow B_{sJ}\) form factors and \(B_c\) decays into \(B_{sJ}\) in covariant light-front approach

We suggest to study the \(B_{s}\) and its excitations \(B_{sJ}\) in the \(B_c\) decays. We calculate the \(B_c\rightarrow B_{sJ}\) and \(B_c\rightarrow B_{J}\) form factors within the covariant light-front quark model, where the \(B_{sJ}\) and \(B_{J}\) denote an s-wave or p-wave \(\bar{b}s\) and \(\bar{b}d\) meson, respectively. The form factors at \(q^2=0\) are directly...
