You can see it in just five lines here, page 1. And an even more compact formulation would just list the symmetry groups, the various fields and how they transform under each group, and would then stipulate that the Lagrangian contains every possible renormalizable term (which is a principle in the construction of such theories, since renormalizable terms that aren’t included get generated anyway).
Uh, wow, that’s a somewhat large equation. It has like 500 terms. Seems… inconsistent with physicists seeing beauty in physics.
