dc.description.abstract | A consistent SU(6) extension of the Weinberg-Tomozawa meson-baryon chiral Lagrangian is constructed which incorporates vector meson and baryon decuplet degrees of freedom. The corresponding Bethe-Salpeter approximation 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. It is the highest hypercharge state of an antidecuplet SU(3) representation and it is unstable through K(*) decay. The estimated width of this state (neglecting d-wave KN decay) turns out to be small (Gamma <= 15 MeV). Clear signals of this resonance would be found in reactions like gamma p ->(K) over bar (0)pK(+)pi(-) by looking at the three body pK(+)pi(-) invariant mass. | |
