We have studied the ππN system and coupled channels by using of the Faddeev equations and two N* and one A states, all of them with jR =1/2+, have been found in the formalism as dynamically generated states. In addition, signatures for a new N* resonance with JR = 1/2+ are found around an energy of 1920 MeV in the three-body center of mass system. 相似文献

We study the properties of charmed hadrons in dense matter within a coupled-channel approach which accounts for Pauli blocking effects and meson self-energies in a self-consistent manner.We analyze the behaviour in this dense environment of dynamically-generated baryonic resonances as well as the open-charm meson spectral functions.We discuss the implications of the in-medium properties of open-charm mesons on the D s0 (2317) and the predicted X(3700) scalar resonances. 相似文献
