Polarized ye− collision

Axion production ina Axion production in unpolarized and polarized ye− collision are considered in detail using the Feynman diagram method. The cross-sections are presented and numerical evaluations are given. The results show that the axion can be dark matter of the universe. Some estimates for experimental conditions are given from our results. unpolarized and polarized ye− collision

Properties of axion production in yu− collision are considered in detail using the the Feynman diagram method. The differential cross-sections are presented and numerical evaluations are given. Based on results obtained it was found that the cross sections depend strongly on the polarization factors of u− beams and are much larger than in axion production in ye- collision. In addition, some estimates for experimental conditions are derived from our results.
