The Price of Tiny Kinetic Mixing
Jörn Kersten, UiB Bergen
Weekly Theory Seminar.
Scenarios with a dark sector involving a light gauge boson have attracted considerable attention recently. The kinetic mixing of such a "dark photon" with the standard photon has to satisfy very stringent experimental bounds, which are violated in the simplest case where kinetic mixing is generated at the one-loop level. I will present scenarios where a sufficiently small kinetic mixing can be obtained.
