The top Yukawa coupling from 10D supergravity with E_8 x E_8 matter
Konstantin Zyablyuk
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…

N=2, D=6 supergravity with E_7 gauge matter
Konstantin Zyablyuk
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 sca…
