N2  - Hadron&#8211;nucleon scattering lengths are studied by the QCD sum rule. First we explain our motivation and present the formulation for calculating hadron-nucleon scattering lengths by the QCD sum rule, where the relation between the hadron mass in the nuclear medium and the hadron&#8211;nucleon scattering length is also clarified. Secondly we discuss two applications, the pion&#8211;nucleon scattering lengths and the nucleon-nucleon scattering lengths. In the case of the pion&#8211;nucleon scattering length we show that the results of the QCD sum rule are consistent with the low-energy theorem. In the case of the nucleon&#8211;nucleon scattering lengths we show that the results of the QCD sum rule are in qualitative agreement with experiment.
