One candidate for it is trinification, which predict magnetic monopoles, while some technicolor models, may also fall into this category. Other candidates include preon models, such as the Harari-Rishon model, while SO10 suffers from the doublet-triplet splitting problem. The flipped SU5 and SU10 models get their name from the flipping of the left-handed fermions relative to the Georgi-Glashow mod

The flipped SU5 and SU10 models get their name from the flipping of the left-handed fermions relative to the Georgi-Glashow model, which predicts proton decay. The Pati-Salam one predicts spontaneous symmetry breaking, but the most famous might be string theory. For ten points, identify these extensions of the Standard Model which seek to incorporate electroweak and strong interactions into a single force.
