【摘要】 在量子场微扰理论的框架内,探讨了轴子探测实验中的轴子电磁衰变机制与衰变振幅.微扰计算结果表明:轴子的电磁衰变振幅与轴子的电磁衰变机制密切相关,由轴子和核子(或夸克)的耦合常数以及核子(或夸克)的质量等因素决定.此结果为进一步研究轴子探测实验中的两类耦合机制之间的关联提供了一种可能的途径.更多还原

【Abstract】 Based on the framework of the perturbation theory of the quantum field, we have explored the mechanism and the amplitude of the electromagnetic decay of the axion in the search for the axion experiments.The result of the perturbation computing shows that the amplitude of the electromagnetic decay of the axion is related to the coupling constant of the axion-nucleon interactions or axionquark interactions,which is closely related to the mechanism of this decay.The amplitude of this electromagnetic decay is also related to the masses of the nucleons or the quarks.This work provides a possible approach to the further research of the relationship between the two types coupling of axion in the search for the axion experiments.更多还原
