Quivers for coloured planar ${\varphi }^n$ theories at all loop orders for scattering processes from Feynman diagrams

Abstract

We introduce Feynman-like rules to compute quivers for two loops and higher for the coloured planar ${\varphi }^3$ theory for winding number zero. We demonstrate this for a few cases. Then we extend this further to the case of ${\varphi }^n$ theories, for any n. We also construct the quivers for mixed theories. We do this at all loop order.
