Dark matter bound state formation in fermionic Z 2 DM model with light dark photon and dark Higgs boson

Abstract If fermionic dark matter (DM) is stabilized by dark U(1) gauge symmetry that is spontaneously broken into its subgroup Z 2, the particle contents of the model becomes very rich: DM and excited DM, both of them are Majorana fermions, as well as two dark force mediators, dark photon and dark...
