| dc.description | In the covariant light-front quark model, we calculate the form factors of $B_c^-\to J/ψ$ and $B_c^-\to X(3872)$. Since the factorization of the exclusive processes $B_c^- \to J/ψπ^-(K^-)$ and $B_c^- \to X(3872)π^-(K^-)$ can be proved in the soft-collinear effective theory, we can get the branching ratios for these decays easily from the form factors. Taking the uncertainties into account, our results for the branching ratio of $B_c^-\to J/ψπ^-(K^-)$ are consistent with the previous studies. By identifying X(3872) as a $1^{++}$ charmonium state, we obtain ${\cal BR}(B_c^-\to X(3872)π^-)=(1.7^{+0.7+0.1+0.4}_{-0.6-0.2-0.4}) \times 10^{-4}$ and ${\cal BR}(B_c^-\to X(3872)K^-)=(1.3^{+0.5+0.1+0.3}_{-0.5-0.2-0.3})\times 10^{-5}$. If assuming X(3872) as a $1^{--}$ state, the branching ratios will be one order magnitude larger than those of $1^{++}$ state. These results can be easily used to test the charmonium description for this mysterious meson X(3872) at LHCb experiment. | |
