A scientist draws a diagram of a hadron on a classroom whiteboard.

Definition

Noun: A hadron is any subatomic particle that is composed of quarks and participates in the strong nuclear force, one of the four fundamental forces in nature. Hadrons are held together by the strong force, which is mediated by particles called gluons.

Examples of Usage

• Noun:
  • Protons and neutrons are stable hadrons found in the nucleus of an atom.
  • The Large Hadron Collider is designed to accelerate and collide hadrons, such as protons.
  • Pions and kaons are examples of mesons, which are one class of hadrons.

Advanced Usage

• "Hadron Collider": A type of particle accelerator that smashes beams of hadrons (like protons or lead ions) together at high speeds to study fundamental physics.
  • Scientists at CERN use the Large Hadron Collider to explore the properties of matter.
• "Hadron therapy": A form of radiation therapy for cancer that uses beams of hadrons, typically protons or carbon ions.
  • Hadron therapy can target tumors more precisely than conventional x-ray radiation.

Variants and Related Words

• Baryon (n): A subclass of hadron made of three quarks. Protons and neutrons are baryons.
• Meson (n): A subclass of hadron made of one quark and one antiquark. Pions are mesons.
• Hadronic (adj): Relating to or involving hadrons.
  • The experiment studied hadronic interactions.

Synonyms

• Strongly-interacting particle: A descriptive synonym emphasizing the defining property of a hadron.

Related Terms (Contextual)

• Lepton (n): The other major class of elementary particles (e.g., electrons, neutrinos) that do feel the strong nuclear force.
• Quark (n): A fundamental constituent of matter that combines to form hadrons.
• Gluon (n): The elementary particle that mediates the strong force, binding quarks together inside hadrons.
