A Perturbative expansion of Beta function - Renormalization

  1. Dec 21, 2016 #1
    I am trying to understand the basics of Renormalization. I have read that β encodes the running coupling and can be expanded as a power series as:

    β(g) = ∂g/(∂ln(μ)) = β0g3 + β1g5 + ...

    However, I don't understand how this is derived.. I assume that the terms correspond to 1 loop, 2 loops etc. Can somebody help me out.
