Hierarchies of Susy Splittings and Invisible Photinos as Dark Matter
Susy Splittings Invisible Photinos Dark Matter
2010/12/24
We explore how to generate hierarchies in the splittings between superpartners. Some of the consequences are the existence of invisible components of dark matter, new inflaton candidates, invisible mo...
SO(10) SUSY GUTs with mainly axion cold dark matter: implications for cosmology and colliders
Supersymmetry Grand unified theories axions
2010/3/16
Supersymmetric grand unified theories based on the gauge group SO(10) are highly motivated. In the simplest models, one expects t-b-\tau Yukawa coupling unification, in addition to gauge, matter and H...
Closing the Window on Strongly Interacting Dark Matter with IceCube
Super-heavy dark matter Simpzillas IceCube
2010/3/15
We use the recent results on dark matter searches of the 22-string IceCube detector to probe the remaining allowed window for strongly interacting dark matter in the mass range 10^4
