How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Towards a Definition of Disentangled Representations (2018, background): “For example, Gell-Mann [32] predicted the existence of a particle called Ω − in 1962 based on the Eightfold Way theory of organising subatomic hadrons according to the ﬂavour symmetries of its constituent quarks.”
A universal qudit quantum processor with trapped ions (2021, methodology): “In the case of a qutrit, the Lie algebra of SU(3) is spanned by the Gell-Mann matrices [22], which are a natural generalization of the Pauli matrices from SU(2) to SU(3), with further generalizations towards SU(d).”
The Spectra of Quantum States and the Kronecker Coefficients of the Symmetric Group (2004, methodology): “in the multiplet theory of Wigner and in the eight-fold way of Ne’eman and Gell-Mann [2, 3, 10, 13].”
Flavor Physics in the Quark Sector (2009, background): “L2 contains the Gell-Mann-Oaks-Renner [120] and Gell-Mann-Okubo [121,122] mass relations and allows one to calculate physical processes, such as ππ scattering, to O(p(2)) in terms of just Fπ and M(2) M (M 2 π = B(mu +md), .”
Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts (2007, background): “Meson nonets SU(3) symmetry considerations have shown to be extremely useful in classifying mesons and baryons [89] as composed of quarks and antiquark or of 3 quarks, respectively.”
