I will briefly introduce superconformal algebras and a few key aspects of their unitary representations. Then I specialize to 4d N=2 superconformal field theories. The main purpose of this talk is to review the spectrum of scaling dimensions of Coulomb branch operators for this class of theories (based on 1801.06554 and 1801.04542). With this knowledge at our disposal we will tackle questions like how many Lagrangian theories there are among all SCFTs (in an asymptotic sense that will be explained and moreover restricted to this special subsector of operators) and more.
