Abstract

We review the case for light U(1) gauge bosons in the hidden‐sector of heterotic and type II string compactifications, present estimates of the size of their kinetic mixing with the visible‐sector hypercharge U(1), and discuss their possibly very interesting phenomenological consequences in particle physics and cosmology.
