Hidden fermion as milli-charged dark matter in Stueckelberg Z' model

Abstract

We augment the hidden Stueckelberg $Z^{\prime }$ model by a pair of Dirac fermions in the hidden sector, in which the $Z^{\prime }$ has a coupling strength comparable to weak scale coupling. We show that this hidden fermion-antifermion pair could be a milli-charged dark matter candidate with a viable relic density. Existing terrestrial and astrophysical searches on milli-charged particles do not place severe constraints on this hidden fermion. We calculate the flux of monochromatic photons coming from the Galactic center due to pair annihilation of these milli-charged particles and show that it is within reach of the next generation $\gamma$-ray experiments. The characteristic signature of this theoretical endeavor is that the Stueckelberg $Z^{\prime }$ boson has a large invisible width decaying into the hidden fermion-antifermion pair. We show that existing Drell-Yan data do not constrain this model yet. Various channels of singly production of this $Z^{\prime }$ boson at the LHC and ILC are explored.
