Scientists make potential breakthrough in search for dark matter
Researchers say the signal has a 0.5% chance of being background, but they caution that one event is not enough to claim dark matter.
- On Tuesday, scientists at the TeV Particle Astrophysics conference in Japan announced a possible dark matter breakthrough, reporting a single particle interaction documented at the Sanford Underground Research Facility in South Dakota.
- Managed by the Lawrence Berkeley National Laboratory, the LUX-ZEPLIN experiment uses 10 tons of liquid xenon buried 1.5 kilometers underground to shield against cosmic rays while searching for Weakly Interacting Massive Particles.
- Researchers identified high-energy event LZ230616 with 2.6 sigma significance, indicating a 0.5 percent chance of background interference; the particle suggests a mass more than 200 times that of a proton.
- Lead author Sam Eriksen of the University of Bristol called it the "most compelling hint reported to date," though the team cautioned the result does not yet meet the 5-sigma discovery threshold.
- The LZ collaboration will continue collecting data until at least 2028 to determine if the signal strengthens or fades; "If it's really dark matter, we'll see more events soon," said theoretical physicist Nicole Bell.
