| dc.description.abstract | Vector meson degrees of freedom are incorporated into the Weinberg-Tomozawa (WT) meson-baryon chiral Lagrangian by using a scheme which relies on spin-flavor SU(6) symmetry. The corresponding Bethe-Salpeter approximation successfully reproduces previous SU(3)-flavor WT results for the lowest-lying s-wave negative-parity baryon resonances, and it also provides some information on the dynamics of the heavier ones. Moreover, it also predicts the existence of an isoscalar spin-parity (3-)(2) K*N bound state (strangeness +1) with a mass around 1.7-1.8 GeV, unstable through K* decay. Neglecting d-wave KN decays, this state turns out to be quite narrow (Gamma <= 15 MeV) and it might provide clear signals in reactions like gamma p -> (K) over bar (0)pK(+)pi(-) by looking at the three-body pK(+)pi(-) invariant mass. | |
