The Model of the Dark Axion Portal

Caption

The new heavy quark is an essential component of many axion models. If this particle has both electromagnetic and dark charges, an axion can interact with the photon and dark photon simultaneously through the heavy quark. While the current axion dark matter search is based on the axion--photon--photon coupling, the new axion--photon--dark photon coupling may provide new search schemes for dark matter.
