DOWN QUARK Meaning and
Definition
-
A down quark is a fundamental particle in the field of particle physics. It is one of the six different types, or flavors, of quarks that make up the building blocks of matter. Along with the up quark, the down quark forms the most familiar type of quark pairing, which constitutes the protons and neutrons in the nucleus of an atom.
Specifically, the down quark is assigned a charge of -1/3e, where e represents the elementary charge. It possesses a lower mass compared to the up quark, with approximately two-thirds the mass of the up quark.
Down quarks have a half-integer spin (or intrinsic angular momentum) of 1/2ħ, obeying the laws of quantum mechanics. They are affected by the strong nuclear force, one of the four fundamental forces of nature, which allows quarks to bind together to form hadrons, such as protons and neutrons.
Apart from being found within atomic nuclei, down quarks are produced in high-energy particle collisions, such as those occurring in particle accelerators, where they are created in pairs alongside other quarks. The behavior and interactions of down quarks are governed by the theory of quantum chromodynamics (QCD), which describes the strong force and its effects on these particles.

Etymology of DOWN QUARK
The word "down quark" is derived from the vocabulary of particle physics, specifically the classification of quarks. Quarks are elementary particles and a fundamental component of matter. They come in six different types or flavors: up, down, charm, strange, top, and bottom.
The term "down" originates from the work of Murray Gell-Mann, an American physicist who proposed the concept of quarks in the 1960s. Gell-Mann was inspired by James Joyce's novel "Finnegans Wake", where the word "quark" appeared as "Three quarks for Muster Mark"! He used the word quark to represent the theoretical particles he was proposing.
Gell-Mann chose the name "down" for one of the quark flavors based on a pattern he noticed.
