Weakly interacting massive particles (WIMPs) are among the leading candidates for dark matter. Experimentalists around the world are searching for the particles in deep underground laboratories, hoping to see WIMPs as they collide with the atoms of a detector, producing nuclear recoils. But a challenge is discriminating a dark matter signal from similar background signals produced by neutrons, neutrinos, and other particles. A comparison of different detection strategies by Julien Billard at the Institute of Nuclear Physics of the University of Lyon, France, highlights those that have the best chance of spotting the elusive particles.

I spot them almost every day. ;-) To read more, click here.
