Antileptons are a fundamental particle in the world of particle physics. They are the antiparticles of leptons and have the same mass as their corresponding leptons but opposite charge. In this article, we will explore the definition, meaning, and origin of antileptons, as well as their associations, synonyms, antonyms, and example sentences.
Definitions
Antileptons are subatomic particles that have the same mass as leptons but carry an opposite charge. They are the antiparticles of leptons, which include electrons, muons, and taus. Antileptons are classified into three types, namely antielectrons (also known as positrons), antimuons, and antitau particles.
Origin
The concept of antiparticles was first introduced by Paul Dirac in 1928, who proposed that every particle in the universe has an antiparticle with the same mass but opposite charge. The existence of antiparticles was confirmed experimentally in 1932 when Carl Anderson discovered the positron, the antiparticle of the electron.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, an antilepton is “a subatomic particle that has the same mass as a lepton but has a charge opposite in sign.” The Oxford English Dictionary defines antilepton as “a subatomic particle that has the same mass as a lepton but carries an opposite charge.”
Associations
Antileptons are associated with the study of particle physics, which is concerned with the behavior and interactions of subatomic particles. They are also associated with antimatter, which is composed of antiparticles and has the same mass as ordinary matter but with opposite charge.
Synonyms
The synonyms of antilepton include antiparticle, antielectron, positron, antimuon, and antitau particle.
Antonyms
The antonyms of antilepton include lepton, electron, muon, and tau particle.
The same root words
The same root words as antilepton include anti-, which means against or opposite, and lepton, which is a type of subatomic particle.
Example Sentences
