The top Yukawa coupling from 10D supergravity with E_8 x E_8 matter
We consider the compactification of N=1, D=10 supergravity with E_8 x E_8 Yang-Mills matter to N=1, D=4 model with 3 generations. With help of embedding SU(5)->SO(10)->E_6->E_8 we find the value of the top Yukawa coupling $λ_t=\sqrt{16πα_{GUT}/3}$ at the GUT scale.

N=2, D=6 supergravity with E_7 gauge matter
The lagrangian of N=2, D=6 supergravity coupled to E_7 X SU(2) vector- and hyper-multiplets is derived. For this purpose the coset manifold E_8/E_7 X SU(2), parametrized by the scalars of the hypermultiplet, is constructed. A difference from the case of Sp(n)-matter is pointed out. This model can be considered as an intermediate step in the compactification of D=10 supergravity coupled to E_8 X E_8 matter to four-dimensional model of E_6 unification.
