New technique uses near-miss particle physics to peer into quantum world − two physicists explain how they are measuring wobbling tau particles

One way physicists seek clues to unravel the mysteries of the universe is by smashing matter together and inspecting the debris. But these types of destructive experiments, while incredibly informative, have limits. We are two scientists who study nuclear and particle physics using CERN’s Large Hadron Collider near Geneva, Switzerland. Working with an international group of nuclear and particle physicists, our team realized that hidden in the data from previous studies was a remarkable and...
