Web7 apr. 2024 · The discovery in the 1970s of the “ charm” (c) and “ bottom” (b) quarks and their associated antiquarks, achieved through the creation of mesons, strongly suggests that quarks occur in pairs. This speculation led to efforts to find a sixth type of quark called “ top ” ( t ), after its proposed flavour . WebBefore the Standard Model was developed in the 1970s (the key elements of the Standard Model known as quarks were proposed by Murray Gell-Mann and George Zweig in 1964), physicists observed hundreds of different kinds of particles in particle accelerators.

Physicists had known that the top must exist since 1977, when its partner, the bottom, was discovered. But the top ... WebIts existence (along with that of the up and strange quarks) was postulated in 1964 by Murray Gell-Mann and George Zweig to explain the Eightfold Way classification scheme of hadrons.
