More effective theory of nuclear forces

Abstract

I outline why the renormalisation group is needed to analyse the scale dependence and hence determine the power counting for effective theories of strongly interacting systems. I summarise the results of several such analyses for two- and three-body forces in nuclear physics. These show that a number of terms should be significantly promoted relative to naive dimensional analysis.
