Muons: 'Strong' evidence found for a new force of nature https://www.bbc.com/news/56643677
quotes: .... There is currently a one in a 40,000 chance that the result could be a statistical fluke - equating to a statistical level of confidence described as 4.1 sigma. A level of 5 sigma, or a one in 3.5 million chance of the observation being a coincidence, is needed to claim a discovery. .... Prof Ben Allanach, from Cambridge University, who was not involved with the latest effort, said: "My Spidey sense is tingling and telling me that this is going to be real. .... The Muon g-2 experiment involves sending the particles around a 14-metre ring and then applying a magnetic field. Under the current laws of physics, encoded in the Standard Model, this should make the muons wobble at a certain rate. Instead, the scientists found that muons wobbled at a faster rate than expected. This might be caused by a force of nature that's completely new to science. .... Harry
