Abstract: Color-kinematics duality and the resulting double copy construction hold for a large class of theories and a lot of work is being done in understanding the underlying principles behind this duality. In this talk, I will discuss the results in arXiv:2204.07130 where we derive a non-perturbative, Lagrangian-level formulation of the double copy in two spacetime dimensions. The results elucidate the field theoretic underpinnings of the double copy in a broad class of scalar theories which can include masses and higher-dimension operators. A corollary to a manifest Lagrangian level color-kinematics duality is an amplitudes-level double copy at all orders in perturbation theory. I will also describe the implementation of the double copy at the level of non-perturbative classical solutions and present a "stringy" generalization.
