Based on the results of the classification by T.-h. Abe, Nucl. Phys. B894, 374 (2015)., we exhaustively investigate Yukawa sector of U(8) model on magnetized orbifolds T2/Z2, T2/Z3, T2/Z4 and T2/Z6 by evaluating ratios of the mass eigenvalues of the three states in all the possible configurations with one and two Higgs pairs where three generations are realized in fermions. Because of the smearing effect via kinetic mixing, one can realize a hierarchy such as 10-2-10-3, but it is very difficult to achieve the mass ratio between the up and top quarks (mup/mtop∼10-5) on the complicated magnetized orbifolds T2/ZN(N=3,4,6). © 2016 American Physical Society.
