We can now give some more detail about the aforementioned free and interaction terms appearing in the Standard Model Lagrangian density. Any such term must be both gauge and reference-frame invariant, otherwise the laws of physics would depend on an arbitrary choice or the frame of an observer. Therefore, the global Poincaré symmetry, consisting of translational symmetry, r… WebKKT method is about optimization of non-linear multivariate functions. The standard model is about Quantum field theory. The term “Lagrangian” came from classical mechanics using the “least action principle”, where the …
