Heavy Quarkonium and QCD Non Relativistic Effective field Theories

Abstract

QCD nonrelativistic effective field theories (NREFT) are the modern and most suitable frame to describe heavy quarkonium properties. In this talk I summarize few relevant concepts and some interesting physical applications of NREFT.
