Electroweak Interaction: Theory & Symmetry

Click For Summary
SUMMARY

The Electroweak Interaction is described by the Electroweak Model, specifically the Weinberg-Salam model, which incorporates the symmetry group SU(2)xU(1). This model effectively unifies the weak nuclear force and electromagnetism under a single theoretical framework. While Quantum Chromodynamics describes the Colour Force and Quantum Electrodynamics addresses Electromagnetism, the Electroweak Model serves as the foundational theory for weak interactions. The term "Quantum Flavordynamics" (QFD) has been mentioned but lacks widespread acceptance in the scientific community.

PREREQUISITES
  • Understanding of Quantum Electrodynamics (QED)
  • Familiarity with Quantum Chromodynamics (QCD)
  • Knowledge of the Standard Model of particle physics
  • Basic concepts of gauge symmetry and group theory
NEXT STEPS
  • Research the Weinberg-Salam model in detail
  • Explore the implications of SU(2)xU(1) symmetry in particle physics
  • Study the differences between Electroweak Theory and Quantum Flavordynamics
  • Investigate current advancements in Quantum Gravity theories
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the unification of fundamental forces in the Standard Model.

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. :)
