Standard Model of Particle Physics

Click For Summary
The standard model of particle physics is based on the local gauge symmetry group SU(3) × SU(2) × U(1). Differential equations governing the fields are derived from the corresponding Lagrangian using the Euler-Lagrange equations, but these equations are complex and not typically examined directly. The equation sought after, as presented by Brian Cox in his TED talk, is difficult to find in a single, clear format online. Variations of the standard model equations exist across different sources, making it challenging to locate a definitive version. Overall, the discussion highlights the complexity and scattered nature of information regarding the standard model.

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 SU(3) \cross SU(2) \cross U(1) 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.
 
Perfect!
Thanks
