A bstract Kinetic mixing between gauge fields of different U (1) factors is a well-studied
phenomenon in 4d EFT. In string compactifications with U (1) s from sequestered D-brane …

A bstract The portal connecting the invisible and visible sectors is one of the most natural
explanations of the dark world. However, the early-time dark matter production via the portal …

A bstract We use Swampland principles to theoretically disfavor regions of the parameter
space of dark matter and other darkly charged particles that may exist. The Festina Lente …

Generic constraints on dark photons are generally presented assuming they have
Stueckelberg masses. These constraints are strengthened if instead the mass is due to the …
