The LZ (LUX-ZEPLIN) experiment, a liquid xenon time-projection chamber located nearly a mile underground at the Sanford Underground Research Facility in South Dakota, set the world's most sensitive limit on WIMP dark matter as of 2024, excluding spin-independent WIMP-nucleon cross sections down to about 2.2 x 10^-48 cm² at 36 GeV/c² WIMP mass — without yet detecting a confirmed dark matter signal.

The LZ (LUX-ZEPLIN) experiment, a liquid xenon time-projection chamber located nearly a mile underground at the Sanford Underground Research Facility in South Dakota, set the world's most sensitive limit on WIMP dark matter as of 2024, excluding spin-independent WIMP-nucleon cross sections down to about 2.2 x 10^-48 cm² at 36 GeV/c² WIMP mass — without yet detecting a confirmed dark matter signal.
The most stringent (lowest) upper limit set on the WIMP-nucleon interaction cross-section by a direct dark-matter detection experiment, at the benchmark WIMP mass where sensitivity is typically reported (around 30-40 GeV/c²).
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
