In a new paper published in the journal Physical Review Letters, we developed a new method with our colleagues for measuring how fast a particle called the tau wobbles.
Our novel approach looks at the times incoming particles in the accelerator whiz by each other rather than the times they smash together in head-on collisions. Surprisingly, this approach enables far more accurate measurements of the tau particle’s wobble than previous techniques. This is the first time in nearly 20 years scientists have measured this wobble, known as the tau magnetic moment, and it may help illuminate tantalizing cracks emerging in the known laws of physics.
