Meaning Behind the Word: Antiparticle

Antiparticle is a fundamental term in the realm of particle physics, often associated with its counterpart in the subatomic world.


An antiparticle is a particle with the same mass but opposite charge to its corresponding particle and is crucial in understanding the symmetry of the universe at the subatomic level.


Here are some examples of antiparticles and their counterparts:

  • Electron: Positron
  • Proton: Antiproton
  • Neutrino: Antineutrino


Antiparticles possess properties like spin, isospin, and baryon numbers opposite to their corresponding particles, making them essential in particle interactions.


Understanding antiparticles has led to the development of technologies such as PET scans, which use positrons for medical imaging, highlighting the practical importance of these subatomic counterparts.


Antiparticles play a significant role in the intricate dance of subatomic particles, shedding light on the fundamental principles governing the universe.
