Confirming the Standard Model: Scientists Measure the Magnetic Moment of the Muon
A new standard of magnetic moment for the muon has been established by an international team of scientists, promising to improve measurements of the muon’s size and shape that could be used to unlock new mysteries of the universe. The new standard was determined using two different experiments that were performed at the Paul Scherrer Institute in Switzerland. The first experiment used an ultrasensitive magnetometer that was able to measure the magnetic field created by the muon with unprecedented precision. The second experiment employed a technique called laser spectroscopy to measure the muon’s energy level to a very high degree of accuracy. By combining the results of these two experiments, the researchers were able to set a new standard for the muon’s magnetic moment with an accuracy of about one part in a trillion. This new level of precision could lead to exciting new discoveries about the nature of the muon and its role in the universe.
