Light on Dark Matter
Galaxies are lighthouses that sit atop peaks in the density field. There is good observational evidence that these lighthouses do not provide a uniform description of the distribution of dark matter.
متن کاملCasting Light on Dark Matter
The prospects for detecting a candidate supersymmetric dark matter particle at the LHC are reviewed, and compared with the prospects for direct and indirect searches for astrophysical dark matter. The discussion is based on a frequentist analysis of the preferred regions of the Minimal supersymmetric extension of the Standard Model with universal soft supersymmetry breaking (the CMSSM). LHC sea...
متن کاملNew light on dark matter.
Dark matter, proposed decades ago as a speculative component of the universe, is now known to be the vital ingredient in the cosmos: six times more abundant than ordinary matter, one-quarter of the total energy density, and the component that has controlled the growth of structure in the universe. Its nature remains a mystery, but assuming that it is composed of weakly interacting subatomic par...
متن کاملBounds on Light Dark Matter
The nature of Dark Matter (DM) is one of the most intriguing questions of modern physics. Its resolution would have a profound impact on the development of particle physics beyond its Standard Model (SM). Although the possibility of having massive compact halo objects (MACHOs) as a dominant form of DM is still under debates (see recent discussion in [1] and references therein), it is widely bel...
متن کاملLight Higgsino Dark Matter
We re–investigate the question whether a light higgsino–like neutralino is a viable Dark Matter candidate. To this end we compute the dominant one–loop corrections to the masses of the higgsino–like states in the minimal Supersymmetric Standard Model (MSSM), due to loops involving heavy quarks and their superpartners. We also calculate analogous corrections to the couplings of higgsino–like neu...
