A scientist observes a mesotron track in a cloud chamber.

Definition

1. Noun:
   • An elementary particle responsible for the forces in the atomic nucleus; a hadron with a baryon number of 0: A "mesotron" is a subatomic particle that mediates the strong nuclear force between protons and neutrons within an atomic nucleus. It is a type of hadron but carries no net baryon number, meaning it is not composed of three quarks like protons and neutrons.

Usage Examples

• Noun:
  • The discovery of the mesotron was a milestone in particle physics.
  • Scientists studied the properties of the mesotron to understand nuclear forces.

Advanced Usage

• Historical Context: The term "mesotron" is an older, now largely obsolete name for what is today universally called a meson. It was used in early particle physics literature.
  • Early papers by Hideki Yukawa referred to the predicted particle as a mesotron.

Variants and Related Words

• Meson (n): The modern term for the class of particles historically called mesotrons. All mesotrons are mesons.
  • Pions and kaons are types of mesons.
• Pion (n): The most common type of meson (mesotron), crucial for holding the atomic nucleus together.
• Hadron (n): The broader category of particles made of quarks that are subject to the strong force; includes both mesons (like the mesotron) and baryons (like protons).

Synonyms

• Meson: The direct and modern synonym.
• Intermediate particle: A descriptive term referencing its role in mediating force.

Notes on Usage

• The word "mesotron" is considered archaic in contemporary scientific discourse. The correct and current term is "meson". You will encounter "mesotron" primarily in historical texts or discussions of the history of physics.
• It is a countable noun (e.g., , ).
