Electroweak Interaction

  1. Dec 9, 2009 #1
    I (moderately) understand the basics of the electromagnetic and weak nuclear forces, but I recently heard of a combined electro-weak theory. It apparently states that two forces are different manifestations of a single force at very high temperatures. Does this mean that the photon (electromagnetic force-carrier) and the W and Z particles (weak force-carriers) are the same particle at that temperature?

    well not the same but they behave as they were the same (photon and Z) with equal strengths.

    By analogy, consider the electric and magnetic forces. They were originally thought to be separate phenomena, but now we know that they're different aspects of the same phenomenon. For example, a purely electric field in one frame of reference will be observed as a mixture of electric and magnetic fields in a different frame of reference. This unifies electricity and magnetism. Unification of electromagnetism with the weak force is another step in the same direction.
