International LZ experiment sees new results in search for dark matter

Using the world’s most sensitive dark matter detector, an international collaboration puts the best-ever limits on particles called WIMPs, a leading candidate for what makes up the universe’s invisible mass.

The nature of dark matter, the invisible substance thought to make up most of the mass in our universe, is one of the greatest mysteries in physics. Using new results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), an international collaboration that includes Penn State researchers has narrowed down the possible properties of one of the leading candidates for the particles that compose dark matter: weakly interacting massive particles, or WIMPs.
