Top Quark

Most massive of all observed elementary particles.

Core Principles & Analysis

• Discovered in 1995 by the CDF and DØ experiments at Fermilab's Tevatron.
• Decays in about 5 × 10⁻²⁵ seconds, too quickly to form hadrons.
• Its enormous mass gives it the strongest coupling to the Higgs field of any known particle.
