Could Physics' Reigning Model Finally Be Dethroned?

New evidence from the world's largest atom smasher, the Large Hadron Collider in Geneva, Switzerland, suggests that certain tiny subatomic particles called leptons don't behave as expected. A single model, called the Standard Model, governs the bizarre world of the teensy tiny. It dictates the behavior of every subatomic particle, from ghostly neutrinos to the long-sought Higgs boson (discovered in 2012), which explains how other particles get their mass.
