Proposed solutions

In M-theory on G 2G_2-manifolds

In the context of M-theory on G2-manifolds (the G2-MSSM) a generic solution to the hierarchy problem is proposed in (Acharya-Kane-Kumar 12, section V.A.2 (p. 10-11)) due to control over non-perturbative effects from membrane instantons, which due to their exponential nature, provide the exponential hierarchy.
