Weak Interactions

  1. Jun 22, 2010 #1
    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. :)
