I'm trying to figure out what the standard model of particle physics is, what is included, who decides what's included, and how one would know when a new concept/theory is included or possibly rejected. It would be great to have a list of recent additions or experimental confirmations. Must everything in the standard model be experimentally verified before inclusion? Is there a standard reference site on Physicsforums? Comment: (I'm not loooking for explicit replies on this laudry list.) I skimmed Wikipedia "Standard Model", and the "mathematical formulation" as well, but I did not see anything explicit about string theory(s) (there are many) , Planck length, Heinseberg uncertainty, Holographic principle, Schrodinger wave equation, Feynman path integrals, nor spin networks to name a few. And I think general relativity and all of gravity is also omitted....unsure about special relativity.....Some sources list QCD others QCD and QED....are these relativistic?/ Many who do not know the fine points of the mathematics, like me, will not be able to tell which of the items listed above, for example, are implicitly included. And I'm guessing there are many other "quantum theories" not included. Thank you.
