Ghost particles, caught cleanly at last: Fermilab's newest detector just published its first results

Neutrinos are ghost-like particles that stream through walls, planets and people without leaving a trace — which makes them maddening to study. Fermilab's newest detector, the Short-Baseline Near Detector in Illinois, has now published its very first results: from thousands of events a day, the team picked out 12,000 especially clean neutrino interactions, with 91% of the selection being the real thing — a sharper picture than earlier experiments managed. It is the groundwork for the giant DUNE experiment, and for the hunt for a possible fourth kind of neutrino that could rewrite what we know about the universe.
