Electroweak Interaction: Theory & Symmetry

Click For Summary

Discussion Overview

The discussion centers on the theoretical framework that describes the Electroweak Interaction, exploring whether it is encapsulated solely within the Electroweak Model or if it has a distinct theoretical identity akin to Quantum Electrodynamics or Quantum Chromodynamics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the specific theory that describes the Electroweak Interaction, questioning if it is simply referred to as Electroweak-Symmetry.
  • Another participant responds by identifying the electroweak symmetry as SU(2)xU(1) and mentions the Weinberg-Salam or Glashow-Weinberg-Salam model as the framework for the Electroweak Interaction.
  • A participant seeks clarification on whether the theory for Weak Interactions is distinct from the Electroweak Model, suggesting a potential equivalence to other fundamental forces' theories.
  • Some participants mention the term "Quantum Flavordynamics" (QFD) as a possible descriptor for the weak interactions, though they note it is not widely recognized.
  • Another participant expresses support for the term QFD, despite acknowledging its lack of clarity for those outside the field.

Areas of Agreement / Disagreement

Participants express differing views on whether the Electroweak Interaction is solely described by the Electroweak Model or if it has its own distinct theoretical framework. The mention of "Quantum Flavordynamics" introduces additional ambiguity, with no consensus reached on its validity or usage.

Contextual Notes

The discussion reflects uncertainty regarding the terminology and theoretical classification of the Electroweak Interaction, with some terms being less established or recognized in the broader scientific community.

I understand that the Colour Force is described by Quantum Chromodynamics, Electromagnetism is described by Quantum Electrodynamics and Gravity will hopefully be described by a Quantum Gravity Theory but currently General Relativity. But what Theory describes the Electroweak Interaction? Is there any specific theory or is it described in Electroweak-Symmetry?

I am not sure if I understood your question correctly but if by electroweak symmetry you mean SU(2)xU(1), then yes. It is generally called Weinberg-Salam or Glashow-Weinberg-Salam model of electroweak interaction.
 
Sorry if I confused you, what I was trying to say is that is the Theory that describes Weak Interactions essentially just described in Electroweak Model or does it have it's own theory?Namely, The Weak Theory (synonymous to Quantum Electrodynamics, Quantum Chromodynamics, Quantum Gravity).

Physiana gave you the correct answer, although just "Electroweak" works too.
 
I've sometimes seen the name "Quantum Flavordynamics" (QFD), although I don't think it's in widespread use.

I don't believe I've heard that before, but on the assumption that it is confusing to the laity, and fanciful, it has my meaningless yet enthusiastic support. :)
