Abstract
The canonical forms associated to scattering amplitudes of planar Feynman diagrams are interpreted in terms of masses of projectives, defined as the modulus of their central charges, in the hearts of certain -structures of derived categories of quiver representations and, equivalently, in terms of cluster tilting objects of the corresponding cluster categories.
