DENVER — Ultracold crystals designed to catch particles of dark matter deep underground have come up with three potential detections, physicists reported April 13 at a meeting of the American Physical Society.

The researchers do not have enough evidence to say they have discovered dark matter particles, but the finding qualifies as a rare clue in the frustrating quest to understand the universe’s most elusive substance.

“We do not believe this result rises to the level of discovery,” said Kevin...
