# The Schwinger model

The Schwinger model is the 2d QED with massless fermions. An important result about it (which I would like to understand) is that this is a gauge invariant theory which contains a free massive vector particle.

The original article by Schwinger "Gauge invariance and mass, II", Phys. Review, 128, number 5 (1962), is too concise for me.

QUESTION: Is there a more detailed/ modern exposition of the above result?

You can take a look at Zinn-Justin, "Quantum field theory and critical phenomena", section 31.4 in 3rd edition.
