/kwɑːk

/ /kwɔːk

noun Physics

Any of a number of subatomic particles carrying a fractional electric charge, postulated as building blocks of the hadrons. Quarks have not been directly observed but theoretical predictions based on their existence have been confirmed experimentally.Research into the atom's nucleus has uncovered a variety of subatomic particles, including quarks and gluons....

This process results in two jets of hadronic particles as the quarks form hadrons.
The scalar superpartners of quarks and electrons are called squarks and selectrons.

Origin

1960s: a word invented by Murray Gell-Man (see Gell-Mann, Murray). Originally quork, the term was changed by association with the line ‘Three quarks for Muster Mark’ in Joyce's Finnegans Wake (1939).

In physics a quark is a type of subatomic particle believed to be one of the basic constituents of matter. The name was coined in the 1960s by the American physicist Murray Gell-Mann, who initially spelt it quork but changed this to quark after he came across the line ‘Three quarks for Muster Mark’ in James Joyce's Finnegans Wake (1939). Joyce's word is meant to suggest the cawing sound seagulls make. It appealed to Gell-Mann, as at the time only three varieties of quark (known as up, down, and strange quarks) were believed to exist.
