antibaryon

Thân thiện

A scientist observes the collision of an antibaryon in a particle detector.

Definition

Noun: - The antiparticle of a baryon: An elementary particle that has the same mass as a corresponding baryon but opposite charge and other quantum properties, such as baryon number. It is a type of hadron.

Examples of Usage

• Noun:
  • The collision produced an antibaryon and a baryon, which subsequently annihilated each other.
  • In particle physics experiments, detecting an antibaryon confirms predictions of antimatter.

Advanced Usage

• In cosmological contexts: Refers to antimatter counterparts of baryonic matter, with implications for understanding the matter-antimatter asymmetry in the universe.
  • The scarcity of antibaryons in the observable universe is a major unsolved problem in physics.

Variants and Related Words

• Baryon (n): A subatomic particle, such as a proton or neutron, that is composed of three quarks and has a baryon number of +1.
• Antiparticle (n): A subatomic particle having the same mass as a given particle but opposite electric or magnetic properties.
• Hadron (n): Any subatomic particle that is subject to the strong nuclear force, including baryons and mesons.

Synonyms

• Antinucleon (when specifically referring to the antiparticles of protons or neutrons).
• Baryonic antiparticle.

Related Terms and Concepts

• Baryon number: A quantum number conserved in particle interactions. Baryons have a baryon number of +1, while antibaryons have a baryon number of -1.
• Annihilation: The process that occurs when a baryon and an antibaryon collide, converting their mass into energy.
