The fermionic partner of the axion

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
