WebAug 3, 2016 · This Is What The Standard Model of Physics Actually Looks Like. We talk a lot about the Standard Model of Particle Physics here at ScienceAlert - you know, the "theory of almost everything" that's the … This article describes the mathematics of the Standard Model of particle physics, a gauge quantum field theory containing the internal symmetries of the unitary product group SU(3) × SU(2) × U(1). The theory is commonly viewed as describing the fundamental set of particles – the leptons, quarks, gauge … See more The standard model is a quantum field theory, meaning its fundamental objects are quantum fields which are defined at all points in spacetime. These fields are • the fermion fields, ψ, which account for "matter particles"; See more As is common in quantum theory, there is more than one way to look at things. At first the basic fields given above may not seem to correspond well with the "fundamental … See more 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 … See more • Overview of Standard Model of particle physics • Fundamental interaction • Noncommutative standard model See more Much of the qualitative descriptions of the standard model in terms of "particles" and "forces" comes from the perturbative quantum field theory view … See more This section provides more detail on some aspects, and some reference material.
