    "abstract": "Re-analyzing the old pi N --\u003e K Lambda data, the additional proof is given\nfor the existence of the N(1710) P11 state, critically needed in light of\nreported observations of exotic Theta(1539) and Xi(1862) pentaquarks. An\nexisting single-resonance model with S11, P11 and P13 Breit-Wiegner resonances\nin the s-channel has been applied. It has been shown that the standard set of\nresonant parameters fails to reproduce the shape of the differential cross\nsection. The new resonance parameter determination has been performed keeping\nin mind the most recent knowledge about nucleon resonances. The extracted set\nof parameters has confirmed the need for the strong contribution of a N(1710)\nP11 resonance. The need for any significant contribution of the P13 resonance\nhas been eliminated. To reproduce the total cross section at the same time with\nthe linear dependence of the differential cross sections with the cos(theta) in\nthe energy range 1650 MeV \u003c W \u003c 1800 MeV the P11 resonance can not but be quite\nnarrow.",
