“…According to [16] chiral superfields in δ(27+27) can be massive through the Yukawa coupling 27 · 27 · 78. If (Z, ρ) = 0 for a component of 27 or 27 with weight ρ, the corresponding chiral superfield gets compactification scale mass, while N f 27 chiral superfields remain massless.…”

Abstract. In the framework of the superstring inspired E 6 model, 'low-energy' extensions of the standard model compatible with leptogenesis are considered and masses of right-handed neutrinos in two scenarios allowed by long-lived protons are discussed. The presence of two additional generations allows breaking of B − L without generating nonzero vacuum expectation values of right-handed sneutrinos of the three known generations. After the symmetry breaking, right-handed neutrinos acquire Majorana masses M ν c ≃ 10 11 GeV. Within the framework of a simple discrete symmetry, assumptions made to provide a large mass of right-handed neutrinos are shown to be self-consistent. Supersymmetric structure of the theory ensures that large corrections, associated with the presence of a (super)heavy gauge field, cancel out.Breaking of B − L in superstring inspired E 6 model.

We apply the solution for the strong CP-problem in the 4-dimensional superstring theory recently proposed by Ibáñez and Lüst to Calabi-Yau type models and study its phenomenological aspects. In Calabi-Yau type models there seem to be phenomenologically difficult problems in the axion decoupling from the neutral gauge currents and the compatibility between the proton stability and the cosmological bound on the axion. DFSZ type invisible axion mechanism which works without heavy extra colored fields may be more promising than KSVZ axion in the viewpoint of proton stability.
