Analysis of the form factors of Bc → D (*), D s (*) and relevant nonleptonic decays*

This study is devoted to calculating the form factors of , , , and transitions in the framework of three-point QCD sum rules. At the QCD side, the contributions of , , , , and are taken into account. With the obtained form factors, the decay widths and branching ratios of several two-body nonleptonic decay processes, , , , , , , , and , are predicted. These results on the form factors and decay properties of the meson provide useful information for us to study the heavy-quark dynamical behavior.
