Standard Model of Particle Physics

Click For Summary

Discussion Overview

The discussion revolves around the Standard Model of particle physics, specifically focusing on locating a visual representation of the model as presented by Brian Cox in a TED talk. Participants also touch on the theoretical framework and mathematical formulation of the Standard Model.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant seeks a specific visual representation of the Standard Model as shown in a TED talk by Brian Cox.
  • Another participant describes the Standard Model as involving the direct product of groups SU(3) × SU(2) × U(1) as a local gauge symmetry group, mentioning the complexity of the differential equations involved.
  • A third participant notes that the representations of the Standard Model are available online in various forms.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants focus on different aspects: one on finding a visual representation, another on the theoretical underpinnings, and a third on the availability of resources.

Contextual Notes

Participants express varying levels of familiarity with the mathematical details of the Standard Model, and there is no resolution on the specific visual representation sought.

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.
 
Perfect!
Thanks
