antibaryon
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.
Noun
-
the antiparticle of a baryon; a hadron with a baryon number of -1
