Title: Constructing Massive Double Copies

Abstract: In this talk, I will give a short introduction to the double copy relation that gives gravity as the ''square'' of Yang-Mills. I will focus on explaining how to extend this relation to the case of massive mediators and explain the issues that arise in this situation. I will mention some standard ways of solving these issues as well as two novel theories that can have well-defined double copies. One consists of a cubic scalar with an additional infinite-dimensional symmetry and the other one consists of topologically massive theories. Time permitting, I will also mention a classical double copy relation that arises for the latter.
