摘要：

We have performed a partial-wave analysis of K+-nucleon scattering in the momentum range from 0 to 1.5 GeV/c addressing the uncertainties of the results and comparing them with several previous analyses. It is found that the treatment of the reaction threshold behavior is particularly important. We find a T=0 scattering length which is not consistent with zero, as has been claimed by other analyses. The T=0 phase shifts for center dot>0 are consistent with a pure spin-orbit potential. Some indications for the production of a T=0 pentaquark with spin-parity-D5/2+ are discussed.
