Gravitino or Axino Dark Matter with Reheat Temperature as high as GeV
Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall
A new scheme for lightest supersymmetric particle (LSP) dark matter is introduced and studied in theories of TeV supersymmetry with a QCD axion, , and a high reheat temperature…
Chiral Dark Sector
Raymond T. Co, Keisuke Harigaya, Yasunori Nomura
We present a simple and natural dark sector model in which dark matter particles arise as composite states of hidden strong dynamics and their stability is ensured by accidental sy…
SaxiGUTs and their Predictions
Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall
We introduce a class of unified supersymmetric axion theories with unified and PQ symmetries broken by the same set of fields at a scale GeV. A typical domai…
