A single flash of light inside a massive underground detector in South Dakota has set off a wave of theoretical activity, as physicists around the world race to determine whether the event marks the first direct detection of dark matter…
The LZ experiment, a liquid xenon detector buried underground in South Dakota, recorded an unusual high-energy particle interaction that researchers say has only a 1-in-200 chance of being a fluke.wmur
Theorists have proposed explanations ranging from higgsinos — superpartners of the Higgs boson — to particles from extra dimensions, since the signal doesn't match standard dark matter models.newscientist
The LZ team is now analyzing 700 days of new data, while independent detectors in Italy and China could eventually corroborate or refute the finding.wmur
