Relic challenges for vector-like fermions as connectors to a dark sector

Autor: Alexandre Carvunis, Navin McGinnis, David E. Morrissey

Abstract New dark sectors consisting of exotic fields that couple only very feebly to the Standard Model (SM) have strong theoretical motivation and may be relevant to explaining the abundance of dark matter (DM). An important question for such secto

Probing the pre-BBN universe with gravitational waves from cosmic strings

Abstract Many motivated extensions of the Standard Model predict the existence of cosmic strings. Gravitational waves originating from the dynamics of the resulting cosmic string network have the ability to probe many otherwise inaccessible propertie

Abstract Vector-like fermions charged under both the Standard Model and a new dark gauge group arise in many theories of new physics. If these fermions include an electroweak doublet and singlet with equal dark charges, they can potentially connect t

Accelerating Earth-Bound Dark Matter

A fraction of the dark matter may consist of a particle species that interacts much more strongly with the Standard Model than a typical weakly interacting massive particle (WIMP) of similar mass. Such a strongly interacting dark matter component cou
