Direct detection of dark matter (DM) requires an interaction particles with nucleons. The same can lead to pair production at a hadron collider, and the addition initial state radiation this may mono-jet signals. Mono-jet searches Tevatron thus place limits on DM direct rates.

The gravitational waves generated wall annihilation have their amplitude and frequency determined by both scale scale. evidence of stochastic at nanohertz observed pulsar timing array experiments suggests discrete-symmetry-breaking around 100 TeV, assuming domain-wall explanation. temperature about MeV,...
