G2-MSSM

The G2-MSSM is a model in particle physics, inspired by KK-compactification of M-theory on a 7-dimensional singular G2-manifold. 

It is hence a model in string phenomenology based on M-theory on G2 manifolds. 

This model is not based on any specific example of a G2 manifold, however, relies on the most general known properties of G2 compactifications of M-theory.
