Detecting Dark Matter with Aharonov-Bohm

Understand

While the evidence for dark matter continues to grow, the nature of the dark matter remains a mystery.

• A dark $U(1)_D$ gauge theory can have a small kinetic mixing with the visible photon which provides a portal to the dark sector.
• Magnetic monopoles of the dark $U(1)_D$ can obtain small magnetic couplings to our photon through this kinetic mixing.
• This coupling is only manifest below the mass of the dark photon; at these scales the monopoles are bound together by tubes of dark magnetic flux.
