The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding--a possible difference in the behavior of different types of lepton particles--chimes with other previous results. If confirmed, as more data are collected and analyzed, the results would signal a crack in the Standard Model.
