Koide Quarks III

On the new Koide thread, Alejandro mentions the Georgi-Jarlskog mass relation. This 1979 relation, which is supposed to hold at high energy, simply states that

$m_b = m_{\tau}$, $m_{\mu} = 3 m_s$, $m_d = 3 m_e$

which uses the original charge quark triplet at $r = 1.76$. This relation arises from (relatively nice) GUT models.

1. Note that Dave's quark triangle has side length $3.04890$, coming from the $1.76$.
