摘要	We study the pi N ->phi N reaction close to the phi N threshold within the chiral unitary approach, by combining the pi(-)p -> K+Sigma(-), pi(-)p -> K-0 Sigma(0), and pi(-)p -> K-0 Lambda amplitudes with the coupling of phi to the K components of the final states of these reactions via quantum loops. We obtain good agreement with experiment when the dominant pi(-)p -> K-0 Lambda amplitude is constrained with its experimental cross section. We also evaluate the couplina of N(1535) to phi N and find a moderate coupling as a consequence of partial cancellation of the large KY components of N(1535). We also show that the N*(1535) pole approximation is too small to reproduce the measured cross section for the pi N- -> phi N reaction.
