Generalized analysis of the direct weakly interacting massive particle searches

Generalized analysis of the direct weakly interacting massive particle searches

We perform a generalized analysis of data from WIMP search experiments for pointlike WIMPs of arbitrary spin and general Lorenz-invariant WIMP-nucleus interaction. We explicitly show that in the nonrelativistic limit only spin-independent ~SI! and spin-dependent ~SD! WIMP-nucleon interactions survive, which can be parametrized by only five independent parameters. We explore this five-dimensiona...

Direct and Indirect Searches for Dark Matter in the Form of Weakly Interacting Massive Particles (wimps)

Numerous lines of evidence indicate that the matter content of the Universe is dominated by some unseen component. Determining the nature of this Dark Matter is one of the most important problems in cosmology. Weakly Interacting Massive Particles (WIMPs) are widely considered to be one of the best candidates which may comprise the Dark Matter. A brief overview of the different methods being use...

On 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) ...

Direct detection of weakly interacting massive particles using non-cryogenic techniques.

A flux of weakly interacting neutral particles incident on the Earth would produce occasional nuclear-recoil events in any material. These could be detected as scintillation or ionization pulses in suitable target materials. Expected rates are in the range 1-10(-4) events kg(-1) d(-1). These must be distinguished from much higher rates due to backgrounds from gamma and beta background, even in ...
