Width of Theta - pentaquarks in relativistic quark model
arXiv:hep-ph/0501267 · doi:10.1142/S0217732305018062
Abstract
The relativistic generalization of Faddeev-Yakubovsky approach is constructed in the form of the dispersion relations. The five-quark amplitudes for the low-lying pentaquarks contain u,d,s-quarks. The poles of these amplitudes determine the masses and widths of Theta-pentaquarks.
