E–WIMPs 1

چکیده
Extremely weakly interacting massive particles (E–WIMPs) are intriguing candidates for cold dark matter in the Universe. We review two well motivated E–WIMPs, an axino and a gravitino, and point out their cosmological and phenomenological similarities and differences, the latter of which may allow one to distinguishing them in LHC searches for supersymmetry.

It is shown that weakly interacting massive particles (WIMPs), which are possible cold dark matter candidates, can be studied by exclusive measurements of X-rays following WIMPs nuclear interactions. Inner-shell atomic electrons are ionized through WIMPs nuclear interaction, and then mono-energetic X-rays are emitted when they are filled by outer-shell electrons. The number of inner-shell holes...

If weakly interacting massive particles (WIMPs) in bound solar orbits are systematically driven into the Sun by solar-system resonances (as Farinella et al. have shown is the case for many Earth-crossing asteroids), then the capture of high-mass WIMPs by the Earth would be affected dramatically because high-mass WIMPs are captured primarily from bound orbits. WIMP capture would be eliminated fo...
متن کاملOn the direct detection of extragalactic weakly interacting massive particles
We consider the direct detection of weakly interacting massive particles (WIMPs) reaching the Earth from outside the Milky Way. If these WIMPs form a distinct population they will, although of much lower flux than typical galactic halo WIMPs, have a number of features which might aid in their ultimate detectability: a high and essentially unique velocity (∼ 600 km/s in the galactic rest frame) ...
متن کاملIMP Distribution In and Evaporation From The Sun
This paper analyzes the evaporation of WIMPS (weakly interacting massive particles) from the sun, both analytically and numerically. First an analytic approximation is made by defining an appropriate truncation of a Maxwell-Boltzmann distribution for the WIMPS and calculating the exact evaporation rate from this distribution due interaction with a truly thermal distribution of nuclei. Then, the...
