"In this picture, we discover that Mp ∝ mt2/27: despite the negligible population of virtual top-antitop pairs in the nucleon, the top-quark mass influences the proton mass."
This is not some wild-eyed vixra prophet of numerology speaking, but Chris Quigg, who has had a long and very respectable career, working especially on hadrons.
Koide-ologists ought to take a keen interest in this claim, for several reasons.
First, the "Brannen phases" for the triples u-c-t, d-s-b, e-mu-tau, are all multiples of 2/27.
Second, the centrality of the top is consistent with Rivero-ist ideas such as the waterfall (in which the quark masses can be understood as arising from a chain of Koide triplets starting with t-b-c) and the sbootstrap (in which all the SM fermions are superpartners of quark-(anti)quark composites of the 5 "light" quarks, i.e. everything but the top) and even "84"-ism.
Third, it legitimizes, in a new way, the appearance of QCD scales as "Brannen mass scales" for e-mu-tau and s-c-b.
