Antiquarks are subatomic particles that are the opposite of quarks, which are the building blocks of protons and neutrons. Antiquarks have a negative charge, whereas quarks have a positive charge. They were first proposed by Murray Gell-Mann in 1964 and have since been observed in particle accelerators.
Definitions
An antiquark is a subatomic particle that has the same mass as a quark but an opposite charge. It is the antiparticle of a quark and is denoted by a bar over the symbol for the quark. Antiquarks are found in particles called mesons and baryons, which are made up of quarks and antiquarks.
Origin
The concept of antiquarks was first proposed by Murray Gell-Mann in 1964 when he was developing the theory of quarks. He suggested that for every quark, there was an opposite particle with the same mass but an opposite charge. This particle was later named the antiquark.
Meaning in different dictionaries
According to the Oxford Dictionary, an antiquark is “a subatomic particle with the same mass as a quark but with an opposite charge, occurring in mesons and baryons.”
The Merriam-Webster Dictionary defines an antiquark as “the antiparticle of a quark that has the same mass but opposite charge and is found in mesons and baryons.”
Associations
Antiquarks are associated with the strong nuclear force, which holds the nucleus of an atom together. They are also associated with the weak nuclear force, which is responsible for radioactive decay.

There are no synonyms for antiquark as it is a specific term used in particle physics.
Antonyms
The antonym of antiquark is quark, which is the particle that antiquarks are the opposite of.
