Investigation of the pentaquark resonance in the NK system
Summary[edit]
| Description |
English: A dynamical calculation of pentaquark systems with quark contents uudd¯s is performed in the framework of a quark delocalization color screening model with the help of the resonating group method. The effective potentials between baryon and meson clusters are given, and the possible bound states or resonances are investigated. The single calculations show that the NK∗ with I=0,JP=12−,ΔK∗ with I=1,JP=12−, and ΔK∗ with I=2,JP=32− are all bound, but they all turn into scattering states by coupling with the corresponding open channels. A possible resonance state ΔK∗ with I=1,JP=52− is proposed. The mass is around 2110.5 MeV, and the decay modes are NK in D wave and NKππ in P waves. |
