Leptons: The Lightweight Particles That Build All Matter
Leptons are elementary particles that do not experience the strong nuclear force, including electrons, muons, taus, and their neutrino partners.
Massless Particles: Why They Must Travel at Light Speed
Massless particles have zero invariant mass and must travel at the speed of light in vacuum. The photon is the only confirmed example.
Fermions: The Particles That Build All Matter
Fermions are half-integer spin particles that obey the Pauli exclusion principle, building all ordinary matter.
Bosons: The Particles That Carry Nature's Forces
Bosons are integer-spin subatomic particles that carry nature's forces and can occupy the same quantum state simultaneously.
Inside the Large Hadron Collider: A Physicist's View
Particle physicist Clara Nellist explains what happens inside the Large Hadron Collider, from a bottle of hydrogen to the discovery of the Higgs...
The Muon g-2 Anomaly That Wasn't
Muon g-2 final result from Fermilab achieves 127 ppb precision, but a revised Standard Model prediction using lattice QCD closes the gap. The...
