Dark matter fermion production
-
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

Dark matter (DM) is a special matter kind. The total amount of dark matter should be around five times bigger than that of ordinary matter. Currently, there are many dark matter models, such as the Cold Dark Matter model with a cosmological constant (ΛCDM) [1] and the vector-fermion dark matter model.
