The full expanded form of the Standard Model Lagrangian. 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 ...
The Standard Model of particle physics is the theory describing three of the ... incorporate the full theory of ... Paul Dirac introduced the Dirac equation, ...
The standard linear solid (SLS), also known as the Zener model after Clarence Zener, [1] is a method of modeling the behavior of a viscoelastic material using a linear combination of springs and dashpots to represent elastic and viscous components, respectively. Often, the simpler Maxwell model and the Kelvin–Voigt model are used. These ...
It is the current standard model of Big Bang cosmology, [1] as it is the simplest model that provides a reasonably good account of: the existence and structure of the cosmic microwave background; the large-scale structure in the distribution of galaxies; the observed abundances of hydrogen (including deuterium), helium, and lithium;

The equations for negative spatial curvature were given by Friedmann in 1924. [2] The physicals models built on the Friedmann equations are called FRW or FLRW models and from the Standard Model of modern cosmology, although such a description is also associated with the further developed Lambda-CDM model. The FLRW model was developed ...
What I would like to see here is the full equation for the standard model, with every variable and operator explained. Something like what's presented here or at 43:16 here. I think its totally fine to have complex terms or functions or operators as long as we link to somewhere where each can be worked out.
Despite being the most successful theory of particle physics to date, the Standard Model is not perfect. [3] A large share of the published output of theoretical physicists consists of proposals for various forms of "Beyond the Standard Model" new physics proposals that would modify the Standard Model in ways subtle enough to be consistent with existing data, yet address its imperfections ...
