I am reading a paper right now on lattice QCD that presents a "method that improves the cooling method and constructs an improved topological charge operator based on the product of link variables forming rectangular Wilson loops."(adsbygoogle = window.adsbygoogle || []).push({});

Unfortunately I am understanding very little of it. It seems like I need some pre-requisite knowledge. The paper makes reference to things like: topological charge, instantons, axial anomalies, etc

I was wondering if someone could point to a resource which could help me understand these concepts
