New calculations seem to have put a 25-year-old particle physics puzzle to rest. But they’ve also created a clash with other experimental results. The post Physicists Solve a Big Quantum Mystery. Now, Old Results Don’t Add Up. first appeared on Quanta Magazine
For 25 years, physicists have been puzzled by an apparent one-part-in-a-million problem. Their expectations of the way that certain particles should wobble in a magnetic field were clashing with what they saw in experiments. The discrepancy was an electrifying hint that they might be seeing evidence of unknown particles. Then in 2021, that hint seemed to evaporate. When researchers updated the…
