Separating astrophysical sources from indirect dark matter signals.
Indirect searches for products of dark matter annihilation and decay face the challenge of identifying an uncertain and subdominant signal in the presence of uncertain backgrounds. Two valuable approaches to this problem are (i) using analysis methods which take advantage of different features in the energy spectrum and angular distribution of the signal and backgrounds and (ii) more accurately...
متن کاملDark Matter from an experimental point of view
If Weakly Interacting Massive Particles (WIMPs) are the Dark Matter in the Galaxy, they can be detected directly in nuclear-recoil experiments or indirectly by observing their annihilation products. Limits obtained by the two techniques can be compared but this comparison requires some hypothesis about the WIMPs cross sections on nuclei and their annihilation branching ratios into neutrinos.
متن کاملDissipative dark matter and the Andromeda plane of satellites
We show that dissipative dark matter can potentially explain the large observed mass to light ratio of the dwarf satellite galaxies that have been observed in the recently identified planar structure around Andromeda, which are thought to result from tidal forces during a galaxy merger. Whereas dwarf galaxies created from ordinary disks would be dark matter poor, dark matter inside the galactic...
متن کاملNeutralino Dark Matter in Focus Point Supersymmetry
In recent work, it has been argued that multi-TeV masses for scalar superpartners are not unnatural. Indeed, they appear to have significant phenomenological virtues. Here we explore the implications of such ‘focus point’ supersymmetry for the dark matter problem. We find that constraints on relic densities do not place upper bounds on neutralino or scalar masses. We demonstrate that, in the sp...
متن کاملDark Matter Detection in Focus Point Supersymmetry
We determine the prospects for direct and indirect detection of thermal relic neutralinos in supersymmetric theories with multi-TeV squarks and sleptons. We consider the concrete example of the focus point region of minimal supergravity, but our results are generically valid for all models with decoupled scalars and mixed Bino-Higgsino or Higgsino-like dark matter. We determine the parameter sp...
