A Unified Theory of Matter Genesis: Asymmetric Freeze-In
Lawrence J. Hall, John March-Russell, Stephen M. West
We propose a unified theory of dark matter (DM) genesis and baryogenesis. It explains the observed link between the DM density and the baryon density, and is fully testable by a co…
Origins of Hidden Sector Dark Matter II: Collider Physics
Clifford Cheung, Gilly Elor, Lawrence J. Hall +1
We consider a broad class of supersymmetric theories in which dark matter (DM) is the lightest superpartner (LSP) of a hidden sector that couples very weakly to visible sector fiel…
Origins of Hidden Sector Dark Matter I: Cosmology
Clifford Cheung, Gilly Elor, Lawrence J. Hall +1
We present a systematic cosmological study of a universe in which the visible sector is coupled, albeit very weakly, to a hidden sector comprised of its own set of particles and in…
