概要

• 論文の詳細を見る

• We study the effect of the fourth generation of quarks and leptons on the third one. We take two typical mass matrices at the grand unified scale: the Fritzsch type and the Stech type ones which are successful in the three generation scheme, and then calculate the evolutions of the Yukawa couplings and the mixing between the third generation quarks and the fourth ones using the renormalization group equations. We investigate them for the three cases: one Higgs doublet model, two Higgs doublets model and supersymmetric model, and obtain a rather large mixing, sinθ=0.02〜0.54 at the electroweak scale.
