dc.description.abstract | We construct a chiral Lagrangian for pentaquark baryons assuming that the recently found Theta(+)(1540) state belongs to an antidecuplet of SU(3) flavor symmetry with J(P) = 1/2 +/-. We derive the Gell-Mann-Okubo formulae for the antidecuplet baryon masses, and a possible mixing between the antidecuplet and the pentaquark octet. Then we calculate the cross sections for pi(-) p -> K(-)Theta(+) and gamma n -> K- Theta(+) using our chiral Lagrangian. The resulting amplitudes respect the underlying chiral symmetry of QCD correctly. We also describe how to include the light vector mesons in the chiral Lagrangian. | - |
