Hadron–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–nucleon scattering length is also clarified. Secondly we discuss two applications, the pion–nucleon scattering lengths and the nucleon-nucleon scattering lengths. In the case of the pion–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–nucleon scattering lengths we show that the results of the QCD sum rule are in qualitative agreement with experiment.

The effect of the vacuum asymmetry [Formula: see text] on π0pp and π0nn coupling constants has been estimated in the QCD sum rules approach. This effect can contribute to charge symmetry breaking in nuclear forces (CSB). The experimental information on CSB is used to estimate εd and the other vacuum asymmetry. [Formula: see text]. It is shown that the values of εs larger than 0.3 still allowed by QCD sum rules in light baryon and meson sectors are not possible.
