| Abstract: | Dark sectors with Abelian gauge symmetries can generically interact with Standard Model particles through kinetic mixing. If monopoles exist in the dark sector and form a sizable component of dark matter, they can affect the survival of the Milky Way's Galactic magnetic field. In this talk I will present results that revise and extend this "Parker Bound" on galactic magnetic energy loss to milli-magnetic monopoles, which leads to the strongest existing constraints on these particles, satisfying our halo ellipticity bounds, over a wide range of dark magnetic monopole masses. | |
