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. | Dark matter fermion production at lepton colliders via photon - dark photon - photon exchange
