Prospects for Indirect Detection of Neutralino Dark Matter
Dark matter candidates arising in models of particle physics incorporating weak scale supersymmetry may produce detectable signals through their annihilation into neutrinos, photons, or positrons. A large number of relevant experiments are planned or underway. The ‘logically possible’ parameter space is unwieldy. By working in the framework of minimal supergravity, we can survey the implication...
متن کاملIndirect Detection of Neutralino Dark Matter
Dark matter detection experiments are getting ever closer to the sensitivity needed to detect the primary particle physics candidates for nonbaryonic dark matter. Indirect detection methods include searching for antimatter and gamma rays, in particular gamma ray lines, in cosmic rays and high-energy neutrinos from the centre of the Earth or Sun caused by accretion and annihilation of dark matte...
متن کاملIndirect Detection of Neutralino Dark Matter
Since neutralinos are Majorana particles, they can annihilate pair-wise and form standard model matter. This can be done either in the dark matter halo itself or once the neutralinos have been gravitationally trapped and have accumulated in the center of the Sun or the Earth. The annihilation products can form detectable uxes, for example in the form of anti-protons or neutrinos. Some character...
متن کاملIndirect Searches for Neutralino Dark Matter
There is mounting evidence for dark matter in the Universe and one of the favourite dark matter candidates is the neutralino, which naturally appears as the lightest supersymmetric particle (LSP) in many supersymmetric extensions of the standard model. The neutralino has the desired properties to be a good dark matter candidate and we will here review the different indirect searches for neutral...
متن کاملIndirect Detection of Neutralino Dark Matter up to TeV Scale
In this paper, we will describe the results of SUSY parameter space searches including minimal supergravity, non-universal supergravity and minimal supersymmetry and the implications on the indirect detection of neutralino dark matter. We give special attention to the effects of detector thresholds, solar absorption of neutrinos and hadronization of neutralino annihilation products. These effec...
