摘要

当质子位于中子附近时，基于静电筛选的简单近似模型，推导出带电和中性介子质量的封闭表达式。估计的质量值与实验测量值的百分之几一致。氘核的电偶极矩也根据这里使用的现象学玩具模型进行了估计。

Simple approximate model for pion masses

Closed expressions for the masses of the charged and neutral pions are derived based on a simple approximate model for electrostatic screening when a proton is located adjacent to a neutron. The estimated mass values agree to a few percent of experimentally measured values. The electric dipole moment of the deuteron is also estimated based on the phenomenological toy model used here.
