摘要：
Possible structures and properties of some excited states of Delta(+)(c) dynamically generated in the coupled-channel P-wave meson-baryon scattering are studied by solving the Bethe-Salpeter(BS) equation in the framework of the Chiral Unitary Approach. It is shown that both Delta(+)(c)(2765) and Delta(+)(c) (2940) could be generated dynamically and could be compound states with multi-configuration molecular-like structures. The couplings of the generated states to various reaction channels are also calculated. Moreover, two highly excited states, Delta(+)(c) (3024) and Delta(+)(c) (3134), are predicted.
