Phys. Rev. C 53, 385–389 (1996)S-wave resonance coupled-channel approach to the reactions π-+p→η+n and K-+p→η+Λ, and a determination of the ηn and ηΛ scattering lengthsReceived 21 November 1994; published in the issue dated January 1996 The total cross sections of the reactions π-+p→η+n and K-+p→η+Λ near threshold have been calculated in an S-wave resonance coupled-channel approach. The ηN scattering length is [0.621±0.040+i(0.306±0.034)] fm and the ηΛ scattering length is [0.64±0.29+i(0.80±0.30)] fm. The large value of the ηΛ scattering length leads us to speculate on the possible existence of η-mesic hypernuclei. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
