RELATIVISTIC FIVE-QUARK EQUATIONS AND A NARROW N*(1688) RESONANCE
2009
International Journal of Modern Physics E
Preserved Fulltext
The relativistic five-quark equations are found in the framework of the dispersion relation technique. The five-quark amplitude for the (1688) resonance including quarks is calculated. The pole of this amplitude determines the mass of non-strange pentaquark M=1686 MeV and the width about 7 MeV. The results are in good agreement with the evidence for a narrow (1688) resonance.
