Inelastic Black Hole Production and Large Extra Dimensions
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
Black hole production in elementary particle collisions is among the most promising probes of large extra spacetime dimensions. Studies of black holes at particle colliders have as…
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…
Graviton Cosmology in Universal Extra Dimensions
Jonathan L. Feng, Arvind Rajaraman, Fumihiro Takayama
In models of universal extra dimensions, gravity and all standard model fields propagate in the extra dimensions. Previous studies of such models have concentrated on the Kaluza-Kl…
Updated Limits on TeV-Scale Gravity from Absence of Neutrino Cosmic Ray Showers Mediated by Black Holes
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
We revise existing limits on the D-dimensional Planck scale M_D from the nonobservation of microscopic black holes produced by high energy cosmic neutrinos in scenarios with D=4+n…
SuperWIMP Dark Matter Signals from the Early Universe
Jonathan L. Feng, Arvind Rajaraman, Fumihiro Takayama
Cold dark matter may be made of superweakly-interacting massive particles, superWIMPs, that naturally inherit the desired relic density from late decays of metastable WIMPs. Well-m…
