Compactifying M-theory over a G-2 manifold reduces the number of generators of this property from 8 to 1. One theory with this property eliminates violations of B and L by introducing R-parity. Solutions that preserve some variations of this property
Compactifying M-theory over a G-2 manifold reduces the number of generators of this property from 8 to 1. One theory with this property eliminates violations of B and L by introducing R-parity. Solutions that preserve some variations of this property are found using Killing spinors (SPINE-oars). A paper in Nature Physics in July 2015 has threatened the viability of this hypothesis, as it confirms the bottom quark's rare transformation into an up quark follows (*) Standard Model predictions. Heavy stable particles predicted by a minimal extension of the Standard Model with this concept could serve as candidates for WIMP dark matter, and that model leads to gauge coupling unification. A possible solution to the hierarchy problem is, for 10 points, this proposed theory from physics that suggests particles possess a partner whose spin differs by a half integer.
