Abstract

We study the hierarchy between M_T , v_L, and v_R, the relevant energy scales of the Minimal Universal Seesaw Model (MUSM), where the two lightest quark families remain massless at tree level. We also predict the heavy top quark mass, m_t′ . We do some numerical analysis using recent experimental data. Our numerical analysis demonstrates that M_T is sensitive to the values of the Yukawa couplings. The heavy top quark mass (m_t′ ) is predicted to be within the range from 1.4 TeV to 7.2 TeV for v_R = 10 TeV.
