The renormalization group equation for large values of the top Yukawa coupling was first considered in 1981 by Pendleton & Ross, and the "infrared quasi-fixed point" was proposed by Hill. The prevailing view at the time was that the top quark mass would lie in a range of 15 to 26 GeV. The quasi-infrared fixed point emerged in top quark condensation theories of electroweak symmetry breaking in which the Higgs boson is composite at extremely short distance scales, composed of a pair of top and anti-top quarks.
