The model was independently proposed by physicists Murray Gell-Mann, [1] who dubbed them "quarks" in a concise paper, and George Zweig, [2] [3] who suggested "aces" in a longer manuscript. André Petermann also touched upon the central ideas from 1963 to 1965, without as much quantitative substantiation.
Both the American physicist Murray Gell-Mann and the Israeli physicist Yuval Ne'eman independently and simultaneously proposed the idea in 1961. [1] [2] [a] The name comes from Gell-Mann's (1961) paper and is an allusion to the Noble Eightfold Path of Buddhism. [3]
In 1961, Murray Gell-Mann introduced the Eightfold Way as a pattern to group baryons and mesons. [11] In 1964, Gell-Mann and George Zweig independently proposed that all hadrons are composed of elementary constituents, which Gell-Mann called "quarks". [12] Initially, only the up quark, the down quark, and the strange quark were proposed. [13]
The physical basis behind both isospin and strangeness was only explained in 1964, when Gell-Mann [9] and George Zweig [10] [11] independently proposed the quark model, which at that time consisted only of the up, down, and strange quarks. [12] Up and down quarks were the carriers of isospin, while the strange quark carried strangeness.
, it was made of three strange quarks, and was discovered in 1964. [3] The discovery was a great triumph in the study of quarks, since it was found only after its existence, mass, and decay products had been predicted in 1961 by the American physicist Murray Gell-Mann and, independently, by the Israeli physicist Yuval Ne'eman. Besides the Ω −

In 1964, Murray Gell-Mann and George Zweig introduced quarks and that same year Oscar W. Greenberg implicitly introduced color charge of quarks. [8] In 1967 Steven Weinberg [ 9 ] and Abdus Salam [ 10 ] incorporated the Higgs mechanism [ 11 ] [ 12 ] [ 13 ] into Glashow's electroweak interaction , giving it its modern form.
