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…
Quest for Black Holes and Superstring Excitations in Cosmic Ray Data
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
In this talk we discuss aspects of TeV-scale gravitational collapse to black holes and string balls and their subsequent evaporation. Special emphasis is placed on the interplay of…
SuperWIMPs in Supergravity
Jonathan L. Feng
In supergravity theories, a natural possibility is that neutralinos or sleptons freeze out at their thermal relic density, but then decay to gravitinos after about a year. The resu…
Supersymmetry and the Linear Collider
Jonathan L. Feng, Mihoko M. Nojiri
We present a pedagogical introduction to supersymmetry and supersymmetric models and give an overview of the potential of the linear collider for studying them. If supersymmetry is…
g_μ- 2 in Supersymmetry
Jonathan L. Feng, Konstantin T. Matchev
The 2.6 sigma deviation in the muon's anomalous magnetic moment has strong implications for supersymmetry. In the most model-independent analysis to date, we consider gaugino masse…
