In an experiment with the catchy name ‘g minus two (g-2)’ the researchers accelerate the sub-atomic particles called muons around a 50-foot-diameter ring, where they are circulated about 1,000 times at nearly the speed of light. The researchers found that they might be behaving in a way that can’t be explained by the current theory, which is called the Standard Model, because of the influence of a new force of nature.
