The Gell-Mann–Nishijima formula, developed by Murray Gell-Mann and Kazuhiko Nishijima, led to the Eightfold Way classification, invented by Gell-Mann, with important independent contributions from Yuval Ne'eman, in 1961. The hadrons were organized into SU(3) representation multiplets, octets and decuplets, of roughly the same mass, due to the ...
However, one of the particles of this decuplet had never been previously observed when the eightfold way was proposed. Gell-Mann called this particle the Ω − and predicted in 1962 that it would have a strangeness −3, electric charge −1 and a mass near 1680 MeV/c 2.
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]
"Quark, Strangeness and Charm" is a 1977 song by the UK rock group Hawkwind, being the title track from the Quark, Strangeness and Charm album. The title references quarks which are sub-atomic particles; "strangeness" and "charm" are playful terms used by physicists to refer to how many strange and charm quarks are within a particle.
Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.

, 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 −
