New experiment hints that a particle breaks the known laws of physics

a close up of a bicycle: The Muon g-2 ring sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the precession (or wobble) of muons as they travel through the magnetic field.

In a landmark experiment, scientists have found fresh evidence that a subatomic particle is disobeying one of science’s most watertight theories, the Standard Model of particle physics. The gap between the model’s predictions and the particle’s newly measured behavior hints that the universe may contain unseen particles and forces beyond our current grasp.

researchers with Fermilab in Batavia, Illinois, announced the first results of the Muon g-2 experiment, which since 2018 has measured a particle called the muon, a heavier sibling of the electron that was discovered in the 1930s.

Like electrons, muons have a negative electric charge and a quantum property called spin, which causes the particles to act like tiny, wobbling tops when placed in a magnetic field. The stronger the magnetic field, the faster a muon wobbles.
