Description
In this talk, I will give a short review on the color-kinematics duality for theories with massive mediators and the issues arising when constructing a double copy. I will focus on two different alternatives that can avoid spurious poles. The first one requires a specific spectrum of masses in the theory and the second uses special kinematics in 3 dimensions. First, I will show how a cubic scalar theory with a special mass spectrum and tuned cubic vertices can give rise to a well-defined double copy. Afterwards, I will focus on the 3d case and explain different double copy constructions for topologically massive theories.
