Narrow Pentaquark States in a Quark Model with Antisymmetrized Molecular Dynamics
The exotic baryon is studied with microscopic
calculations in a quark model by using a method of antisymmetrized molecular
dynamics(AMD). We predict narrow states, ,
, and , which nearly degenerate in a
low-energy region of the system. We discuss decay widths and
estimate them to be for the , and
MeV for the state.Comment: Talk given at International Workshop on PENTAQUARK04, Spring-8,

Magnetic moment of the pentaquark with light-cone QCD sum rules
In this article, we study the magnetic moment of the pentaquark state as diquark-diquark-antiquark () state in the
framework of the light-cone QCD sum rules approach. The numerical results
indicate the magnetic moment of the pentaquark state is about
