Direct Detection of WIMPs
In the next chapters we are going to give an overview of the main WIMP search strategies, which fall in three big categories: • Direct searches probe the scattering cross section of WIMPs with nuclei, by looking for nuclear recoils in some target material in a low background environment. When a WIMP of the galactic halo passes through the target, it may scatter off a nucleus, whose recoil will ...

متن کاملDirect Detection of Multi-component Secluded WIMPs
Dark matter candidates comprising several sub-states separated by a small mass gap ∆m, and coupled to the Standard Model by (sub-)GeV force carriers, can exhibit nontrivial scattering interactions in direct detection experiments. We analyze the secluded U(1)S-mediated WIMP scenario, and calculate the elastic and inelastic cross sections for multi-component WIMP scattering off nuclei. We find th...
متن کاملDirect and Indirect Detection of Wimps
We present here the principles of detection of Weakly Interacting Massive Particles , which could represent a large contribution to Dark Matter. A status of the experimental situation is given both for indirect and direct detection. In particular , the DAMA claim for a WIMP signal is confronted to the recent results of the CDMS and EDELWEISS experiments. We conclude by comparing direct and indi...
متن کاملOn the Direct Detection of Extragalactic WIMPs
We consider the direct detection of 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) due to their acceleration in entering t...
