We construct a relativistic and unitary approach to 'high' energy pion-and photon-nucleon reactions taking the ฯ€N, ฯ€โˆ†, ฯN, ฯ‰N, ฮทN, Kฮ›, Kฮฃ final states into account. Our scheme dynamically generates the s-and d-wave nucleon resonances N(1535), N(1650) and N( ) and isobar resonances โˆ†(1620) and โˆ†(1700

And it is found that both sets lead to invariant amplitudes which are not kinematical singularity and zero free. where the K,(p)-standard covariants carry spin-tensorial indices and are polynomial in the four-vectors p = (pl ,...,pn ) [9]. The invariant amplitudes Ai( which are functions of the ind
