AbstractWe have proposed to use an effective theory to describe interactions of an N (N) over bar system. The effective theory can be constructed in analogy to the existing effective theory for an NN system. In this work we study the next-to-leading order correction to N (N) over bar scattering near the threshold in the effective theory. We find that the experimental data can be well described with the effective theory.
