Standard Model of Particle Physics

In summary, the standard model of particle physics is based on the direct product of groups SU(3) \cross SU(2) \cross U(1) and is described by complicated differential equations derived from the Euler-Lagrange field equations. The equation is available online but in slightly different versions.

Does anyone know where to find the standard model of particle physics shown by Brian Cox in his LHC TED talk (found around 6:35 here: http://www.youtube.com/watch?v=_6uKZWnJLCM)? I'm looking to print out the equation but can't find it anywhere.

Thanks

The standard model of particle physics is the assertion that the direct product of groups [itex]SU(3) \cross SU(2) \cross U(1)[/itex] is a local gauge symmetry group in spacetime. In the standard model, differential equations for the field (analogous to Maxwell's equations) are determined by inserting the appropriate Lagrangian for that field into the Euler-Lagrange field equations.

In other words, the differential equations that describe the fields in the standard model are so complicated that we never look at them directly.

What is the Standard Model of Particle Physics?

The Standard Model of Particle Physics is a theory that describes the fundamental building blocks of matter and the forces that govern their interactions. It explains how particles such as quarks, leptons, and bosons interact with each other to form the universe as we know it.

What are the particles included in the Standard Model?

The Standard Model includes six types of quarks, six types of leptons, and four types of force-carrying bosons. Quarks make up particles such as protons and neutrons, while leptons include particles such as electrons and neutrinos. The four bosons are the photon, W and Z bosons, and the gluon.

What are the four fundamental forces described by the Standard Model?

The four fundamental forces described by the Standard Model are gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. Gravity is responsible for the attraction between objects with mass, electromagnetism governs electric and magnetic interactions, the strong force holds atomic nuclei together, and the weak force is responsible for radioactive decay.

What evidence supports the Standard Model?

There is a significant amount of evidence that supports the Standard Model, including experimental data from particle accelerators, observations of the behavior of particles in nature, and successful predictions of new particles. The discovery of the Higgs boson in 2012 was a major confirmation of the Standard Model.

What are the limitations of the Standard Model?

The Standard Model does not include gravity and does not fully explain dark matter and dark energy, which are thought to make up a significant portion of the universe. Additionally, it does not account for the hierarchy of particle masses or the asymmetry between matter and antimatter. These limitations suggest that there may be more to the fundamental laws of nature than what is described by the Standard Model.
