  An effective Lagrangian model in a coupled channels framework is applied to
extract nucleon resonance parameters. In the K-matrix approximation, we
simultaneously analyze all the available data for the transitions from pi N to
five possible meson-baryon final states, pi N, pipi N, eta N, K Lambda, and
KSigma, in the energy range from pi N threshold up to W = 2 GeV. In this work,
we focus our efforts on the K Sigma channel. In particular, we include a set of
Delta resonances around 1900 MeV: the S31(1900), P31(1910), and P33(1920)
states. In most cases the parameters of nucleon resonances determined by the
fits are consistent with the commonly accepted values in the literature. We
find that in the low-energy region, the S11(1650), P11(1710), and P13(1720)
states are important for the p(pi-,K0)Sigma0 and p(pi-,K+)Sigma- processes
while the P33(1600) and D33(1700) states are significant for the pure I=3/2
reaction p(pi+,K+)Sigma+. In the high energy region, we find a D13 state at
1945 MeV which is important for the p(pi-,K0)Sigma0 reaction while the Delta
resonances around 1900 MeV show up significantly in the p(pi-,K+)Sigma- and
p(pi+,K+)Sigma+ processes.
