中文摘要：

Possible structures and properties of some excited states of Λ 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 Λ c + (2765) and Λ 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,Λ c + (3024) and Λ c + (3134),are predicted.

英文摘要：

Possible structures and properties of some excited states of ∧^＋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 ∧^＋c（2765） and ∧^＋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, ∧^＋c（3024） and ∧^＋c（3134）, are predicted.
