description Standard Model Overview
The Standard Model is a theoretical framework describing fundamental particles and forces—electromagnetic, weak, and strong—excluding gravity, and categorizing them into quarks, leptons, and bosons.
help Standard Model FAQ
What particles are included in the Standard Model?
The Standard Model includes quarks, leptons, gauge bosons, and the Higgs boson. It organizes matter particles into three generations, including electrons, neutrinos, up quarks, and down quarks.
Which forces does the Standard Model describe?
It describes electromagnetism, the weak nuclear force, and the strong nuclear force. It does not include gravity, which is one major reason physicists treat it as incomplete.
Why was the Higgs boson discovery important?
The Higgs boson was discovered at CERN's Large Hadron Collider in 2012 by the ATLAS and CMS experiments. Its discovery supported the Higgs mechanism, which explains how many elementary particles acquire mass.
What does the Standard Model fail to explain?
It does not explain dark matter, dark energy, gravity, or why neutrinos have mass. It also does not explain the matter-antimatter imbalance observed in the universe.
