Sentences with phrase «wimp interactions»

No experiment has yet conclusively detected WIMPs, but CDMS has set the most stringent limits of any experiment on the strength of WIMP interactions with ordinary matter.

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

The detector material is surrounded by arrays of photomultiplier tubes (PMTs) to capture the light from potential WIMP interactions.

Not exact matches

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.

Because of uncertainties over the exact mass and interaction strength of these elusive particles, the WIMP search space spans eight orders of magnitude.

Even with just a few detection events — «maybe five,» Sadoulet suggests — CDMS should be able to make a lower limit estimate of WIMP mass and get an idea of the interaction rate, giving us a first glimpse at the properties of the cosmic dark stuff.

If WIMPs exist, they are very common, but they usually pass through ordinary matter without interaction.

Some models predict that EGB gamma rays could arise from distant interactions of dark matter particles, such as the annihilation or decay of WIMPs.

After each non-detection, McGaugh says, theorists continually redefine the interaction cross-section of WIMPs to safely undetectable levels.

The published results of these studies have set stringent limits on the mass ranges and interaction rates for many proposed WIMPs, even eliminating some models.

Yet if one of these particles (which could be a WIMP) were responsible for dark matter, most versions of the theory would not predict self - interactions.

With an expected mass of 50 - 1,000 billion electron volts (GeV)-- the mass of a proton is 1 GeV — and weak interaction with everyday matter, the neutralino is a prime candidate for being a WIMP.
