First-Ever Evidence of Higgs Boson Decay Opens New Doors for Particle Physics

By Don Lincoln last updated

For the first time, scientists at the Large Hadron Collider have unambiguously detected Higgs bosons decaying into a matter-antimatter pair of bottom quarks.

Particle Physics
An ATLAS candidate event for the Higgs boson particle decaying into two bottom quarks. Physicists at CERN recently observed this process, which further confirms the Standard Model of particle physics.

The standard model of particle physics may be broken — an expert explains

By Roger Jones published

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from what is expected.
