Photon properties from gauge theories

  1. Jul 28, 2012 #1
    Hello everyone,

    I read on Wikipedia that a lot of the properties of photons are explained by them being the quanta of an abelian gauge field (link).

    Does anyone happen to have a good source on this? I haven't learned anything about gauge theories yet, so I'm looking for an introductory text. So far I've only been able to find very tough textbooks on the matter.

    Thank you in advance,

    A very important concept is the reduction of the four-potential Aα to the two transversal and physical polarizations. This is achieved by gauge symmetry.

    I can't recomment this book; it's partially rather confusing, especially when it comes to intuitio and explanations.
