SuperWIMP Cosmology and Collider Physics
Jonathan L. Feng, Arvind Rajaraman, Bryan T. Smith +2
Dark matter may be composed of superWIMPs, superweakly-interacting massive particles produced in the late decays of other particles. We focus here on the well-motivated supersymmet…
SuperWIMP Dark Matter in Supergravity with a Gravitino
Jonathan L. Feng, Shufang Su, Fumihiro Takayama
We investigate the superWIMP scenario in the framework of supersymmetry, in which the lightest supersymmetric particle is a stable gravitino. We consider slepton, sneutrino or neut…
Supergravity with a Gravitino LSP
Jonathan L. Feng, Shufang Su, Fumihiro Takayama
We investigate supergravity models in which the lightest supersymmetric particle (LSP) is a stable gravitino. We assume that the next-lightest supersymmetric particle (NLSP) freeze…
SuperWIMP Gravitino Dark Matter from Slepton and Sneutrino Decays
Jonathan L. Feng, Shufang Su, Fumihiro Takayama
Dark matter may be composed of superWIMPs, superweakly-interacting massive particles produced in the late decays of other particles. We focus on the case of gravitinos produced in…
