The Crystal Ball Collaboration has recently reported the differential cross sections and A polarization for the reaction K- p ->pi(0)A using an incident K- beam with momenta between 514 and 750 MeV/c. We make an analysis for this process with an effective Lagrangian approach and study the properties of some Sigma resonances around this energy range. With the inclusion of the 4-star resonances Sigma(1189), Sigma*(1385), Sigma(1670)3(-)/2 , Sigma(1775)5(-)/2, as well as a Sigma(1635)1(+)/2, which is compatible with the 3-star Sigma(1660)1(+)/2 in PDG, our results can well reproduce the experimental data. The parameters on the Z resonances and related couplings are studied. (C) 2011 Elsevier B.V. All rights reserved.
