| Abstract: | We show that after the gauge symmetry breaking of the E6 grand unified group to the H=SU(3)c×SU(2)L×U(1)Y× U(1)E subgroup by the Hosotany mechanism a number of additional Yukawa terms not present in a decomposition of 27×27×27 may appear in the low energy superpotential. Some of these terms cause a rapid proton decay. |
