Odd Parity Light Baryon Resonances

Understand

We use a consistent SU(6) extension of the meson-baryon chiral Lagrangian within a coupled channel unitary approach in order to calculate the T-matrix for meson-baryon scattering in s-wave.

• The building blocks of the scheme are the pion and nucleon octets, the rho nonet and the Delta decuplet.
• We identify poles in this unitary T-matrix and interpret them as resonances.
• We study here the non exotic sectors with strangeness S=0,-1,-2,-3 and spin J=1/2, 3/2 and 5/2.
