The top Yukawa coupling from 10D supergravity with E8 x E8 matter
Konstantin Zyablyuk
Abstract
We consider the compactification of N=1, D=10 supergravity with E8 x E8 Yang-Mills matter to N=1, D=4 model with 3 generations. With help of embedding SU(5)->SO(10)->E6->E8 we find the value of the top Yukawa coupling λt=16παGUT/3 at the GUT scale.
