$N\bar{N}$ Scattering at NLO Order in An Effective Theory

Abstract

We have proposed to use an effective theory to describe interactions of an $N\bar{N}$-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 $N\bar{N}$ scattering near the threshold in the effective theory. We find that the experimental data can be well described with the effective theory.
