有效理论中的NLO阶$N\bar N$散射

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

G. Y. Chen, J. P. Ma

摘要:

我们提出了一个有效的理论来描述一个$N\bar N$ -系统的相互作用。该有效理论可以类似于现有的$NN$ -系统的有效理论来构造。本文研究了在有效理论中,在阈值附近对$N\bar N$散射的次前阶修正。我们发现,实验数据可以很好地描述与有效的理论。

英文摘要:

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.
