Key guiding question: what are the compatibilities and incompatibilities on the geometric level before the theory is created quantum mechanical.
- From Einstein's general relativity, we take the Einstein projection of the curvature tensor of the Levi-Civita connection of the metric $$P_E(F_{\Delta^LC})$$
- From Yang-Mills-Maxwell-Anderson-Higgs theory of gauge fields, we take the adjoint exterior derivative coupled to a connection $$d^\star_A F_A$$
Question: What if the $$F$$'s are the same in both contexts?
Then we're applying two different operators. The Einstein projection operator is zeroth order, it's destructive in the sense that it doesn't see the entire curvature tensor. The adjoint exterior derivative operator is inclusive but of first order.
Question: Is there any opportunity to combine these two operators?
A problem is that the hallmark of the Yang-Mills theory is the freedom to choose the data, the internal quantum numbers that give all the particles their personalities beyond the mass and the spin. We can allow the gauge group of symmetries to act on both sides of the equation, but the key problem is that: $$P_E(F_{\Delta^{LC} h}) \neq h^{-1} P_E(F_{\Delta^{LC} }) h $$. If we act on connections on the right and then take the Einstein projection, this is not equal to first taking the projection and then conjugating with the gauge action.
Layman Explanation
a theory is like a newspaper story
- where/when -> space/time
- who/what -> fermions/bosons
- how/why -> rules/what generates the rules (equations and lagrangians)
