2.It is shown that Lagrangian density operator of electromagnetic interaction should satisfy elementary conditions of Hermitian , gauge invariance, and the character of Lorentz scalar operator , we expand the traditionalelectromagnetic decay effective theory into the situation ,which includes many neutral mesons based on the idea of S.电磁相互作用拉氏密度量算子应满足的厄密性和规范不变性基本要求,同时还应满足Lorentz标量算子特性,而“传统”电磁衰变有效理论虽满足上述条件但不能同时很好地描述多个中性赝标介子电磁衰变成双光子的问题。

电磁衰变通过电磁相互作用，一个微观粒子衰变为其他一些微观粒子的过程。最早观察到的亚原子粒子的电磁衰变现象是原子核的γ跃迁。在这个过程中原子核由激发态跃迁到较低的能级同时放出一个光子。有一些介子和重子有相当大的电磁衰变几率。如中性的π介子几乎全部通过电磁作用衰变为两个光子或一个光子和一个正负电子对（见衰变分支比）。中性的Σ重子几乎全部衰变为Σ 重子和一个光子。由于电磁作用比弱作用强，电磁衰变的粒子的寿命比只能弱衰变的粒子的寿命短得多。
