Description
Within the scattering amplitudes bootstrap program, I will present new hierarchical constraints on the symbol of the Feynman integral: genealogical constraints, which hold to all orders in dimensional regularisation. These constraints apply at any loop order, particle multiplicity, and for any configuration involving massive or massless virtual particles. I will also explain how one can find the hierarchical constraints without solving Landau equations explicitly, relying instead on minimal information about the integral’s kinematic singularities.
