LHCb has described an “indication” (which is a weaker statement than saying “discovery”) that they have observed a difference in the way electrons and muons behave. There is something different from what the Standard Model predicts. They are cautious to say that the statistical significance is not sufficient for it to be termed a discovery. With the next runs bringing in some five times more data it is very possible that they would get a stronger indication of this. The results could lead to the discovery of new particles or even new forces that could help explain the Universe’s mysteries, like dark matter. Data from the Large Hadron Collider is testing the boundaries.
