| Abstract: | A mechanism of symmetry breaking by the Wilson loop is discussed. In particular, we take the Wilson loop to break the E6 symmetry of superstring theory down to SU(6)×U(1)T3R and then to SU(3)L×U(1)Y in succession. By the fine tuning parameters we obtain sin2θW=0.215, the proton life time τp≈1034yr and the two intermediate mass scales MI≈1016−17 GeV and MII≈105−10 GeV. |
