Most WIMP detectors are placed deep underground to shield them from background radiation that can cloud that signal.

The mechanism for this asymmetry is still unclear, but if something similar happened for dark matter, it should be made of lightweight particles of about 5 to 10 gigaelectronvolts — just below what WIMP detectors can see.

The «WIMP wars» have raged since 1998, when the DAMA experiment in the Gran Sasso lab in Italy claimed its detector was sparkling with particles that could be WIMPs.

Before the recent finding, some theorists had speculated that the Higgs hadn't shown up yet because it decayed into two dark matter particles, or WIMPs (weakly interacting massive particles), which would be invisible to the LHC's detectors.

Researchers are building ever - larger detectors, retooling their experiments and continuing to expand the search beyond WIMPs.

WIMP champions are pinning their hopes on more sensitive underground detectors that are running or under construction.

On one hand, their new constraints on the plausible masses and interactions of WIMPs are priming plans for next - generation detectors that could offer better chances of success.

But alternative explanations have not been ruled out, and other detection techniques have yet to pan out — like waiting for a WIMP to smack into an underground detector such as LUX in South Dakota (pictured above) or creating one at a particle accelerator, for example.

By building larger detectors to get more hits, researchers will be better able to characterize WIMPs.

While the results did not detect dark matter particles — known as «weakly interacting massive particles» or «WIMPs» — the combination of record low radioactivity levels with the size of the detector implies an excellent discovery potential in the years to come.

In theory, millions of WIMPs pass through the detector stacks every second.

The Cryogenic Dark Matter Search (CDMS) is an experiment that uses superconducting detectors to search for rare WIMP interactions.

When a particle (such as a WIMP) collides with the detector, it creates crystal lattice vibrations (phonons) and releases electrons.

Physicists hope to detect it in the form of weakly interacting massive particles (WIMPs) when they collide with ordinary matter in underground detectors.

To calibrate the LUX for low - mass WIMPS, the LUX team fired low - mass neutrons directly into the detector and used the detector's instruments precisely measure the characteristics of the neutron recoil.

«You want to be able to measure your detector response for WIMP - like events.»

The experiment monitors germanium detectors, cooled to a fraction of a degree above absolute zero, for subtle vibration and ionization effects that would be produced by WIMPs colliding with germanium nuclei.

The key is how well LUX researchers have calibrated their detector and whether they can show that it's truly sensitive to low - mass WIMPs, says Juan Collar, a physicist at the University of Chicago in Illinois and leader of the CoGeNT team.

If a WIMP strikes a xenon nucleus with the LUX detector, the recoiling nucleus should produce telltale flashes of light.

WIMPs in this dense disc would be more likely to hit a detector but as they are keeping pace with Earth in its flight around the galaxy, they would collide with less energy than expected.

Lack of sensitivity in these detectors may explain why WIMPs have evaded direct detection so far.

Therefore, most detectors have been built to detect particles the size of WIMPs, thought to weigh more than 100 times the mass of a proton.

TKF: In bubble chamber detectors, WIMP collisions are expected to generate a single bubble, while other, more energetic particles are expected to trigger bubble tracks.
