Abstract

SU(2)L doublet Higgs fields are unified with gauge fields in the U(3)s × U(3)w model of Antoniadis, Benakli and Quirós' on the orbifold M4 × (T2/Z2). The effective potential for the Higgs fields (the Wilson line phases) is evaluated. The electroweak symmetry is dynamically broken to U(1)EM by the Hosotani mechanism. There appear light Higgs particles. There is a phase transition as the moduli parameter of the complex structure of T2 is varied.
