The $I^¥ (n S) \to B_{(c)}$ transition form factors and their applications to semileptonic and nonleptonic weak decays

You-Ya Yang, Zhi-Qing Zhang, Zhi-Jie Sun

The semileptonic and nonleptonic decays of the $I^¥ (n S)$ with $n = 1, 2, 3, 4$ are investigated within the covariant light-front quark model (CLFQM). Using the form factors of the transi…
