Efficient Hilbert Series for Effective Theories

Abstract:
The task of finding ope​rator bases for effective theories can be assisted by using the Hilbert series, which counts the number of independent operators at a given effective order. In this talk I will introduce the Hilbert series for Standard Model Effective Theory and some extensions, and present ECO, a FORM based implementation that can be used to efficiently establish the number of operators at effective orders as high as 20 (or more). I will discuss some applications, and give an outlook on interesting extensions to other effective theories.
