QCD renormalization for the top-quark mass in a mass geometrical mean hierarchy

Abstract

$QCD$ renormalization for the top-quark mass is calculated in a mass geometrical mean hierarchy, $m_d{m}_b=m_s^2$ and $m_u{m}_t=m_c^2$. The physical mass, $m_t(m_t)=160\pm 50GeV$ is obtained, which agrees very well with electroweak precision measurement.
