Inflationary Gravitational Leptogenesis
Raymond T. Co, Yann Mambrini, Keith A. Olive
We consider the generation of the baryon asymmetry in models with right-handed neutrinos produced through gravitational scattering of the inflaton during reheating. The right-hande…
New Horizons: Scalar and Vector Ultralight Dark Matter
D. Antypas, A. Banerjee, C. Bartram +123
The last decade has seen unprecedented effort in dark matter model building at all mass scales coupled with the design of numerous new detection strategies. Transformative advances…
New Ideas in Baryogenesis: A Snowmass White Paper
Gilly Elor, Julia Harz, Seyda Ipek +21
The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of the Universe. This observation is a clear sign of new physics beyond the Standard Model. Ther…
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…
