Fano and Reflexive Polytopes from Feynman Integrals

Leonardo de la Cruz, Pavel P. Novichkov, Pierre Vanhove

We classify the Fano and reflexive polytopes that arise from quasi-finite Feynman integrals. These polytopes appear as scaled Minkowski sums of the Newton polytopes associated with…

Polytope symmetries of Feynman integrals

Leonardo de la Cruz

Feynman integrals appropriately generalized are -hypergeometric functions. Among the properties of -hypergeometric functions are symmetries associated with th…

Algorithm for differential equations for Feynman integrals in general dimensions

Leonardo de la Cruz, Pierre Vanhove

We present an algorithm for determining the minimal order differential equations associated to a given Feynman integral in dimensional or analytic regularisation. The algorithm is…

Holonomic representation of biadjoint scalar amplitudes

Leonardo de la Cruz

We study tree-level biadjoint scalar amplitudes in the language of -modules. We construct left ideals in the Weyl algebra that allow a holonomic representation of -point…

Classical off-shell currents

Francesco Comberiati, Leonardo de la Cruz

We consider tree-level off-shell currents of two massive particles and massless bosons in the classical limit, which can be fused into the classical limit of scattering a…

On kinetic theories with color and spin from amplitudes

Leonardo de la Cruz

We extend a previously developed approach to relate thermal currents in the high temperature regime and classical limits of amplitudes. We consider the bi-adjoint scalar theory, wh…

Light bending from eikonal in worldline quantum field theory

Fiorenzo Bastianelli, Francesco Comberiati, Leonardo de la Cruz

Using the worldline quantum field theory (WQFT) formalism for classical scattering, we study the deflection of light by a heavy massive spinless/spinning object. WQFT requires the…

Yang-Mills observables: from KMOC to eikonal through EFT

Leonardo de la Cruz, Andres Luna, Trevor Scheopner

We obtain a conservative Hamiltonian describing the interactions of two charged bodies in Yang-Mills through and to all orders in velocity. Our calculation exten…

Worldline description of a bi-adjoint scalar and the zeroth copy

Fiorenzo Bastianelli, Francesco Comberiati, Leonardo de la Cruz

Bi-adjoint scalars are helpful in studying properties of color/kinematics duality and the double copy, which relates scattering amplitudes of gauge and gravity theories. Here we st…

Properties of scattering forms and their relation to associahedra

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

We show that the half-integrands in the CHY representation of tree amplitudes give rise to the definition of differential forms -- the scattering forms -- on the moduli space of a…

Relations for Einstein-Yang-Mills amplitudes from the CHY representation

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

We show that a recently discovered relation, which expresses tree-level single trace Einstein-Yang-Mills amplitudes with one graviton and gauge bosons as a linear combinati…

Double copies of fermions as only gravitational interacting matter

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

Inspired by the recent progress in the field of scattering amplitudes, we discuss hypothetical particles which can be characterised as the double copies of fermions -- in the same…

Proof of the fundamental BCJ relations for QCD amplitudes

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

The fundamental BCJ-relation is a linear relation between primitive tree amplitudes with different cyclic orderings. The cyclic orderings differ by the insertion place of one gluon…

The CHY representation of tree-level primitive QCD amplitudes

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

In this paper we construct a CHY representation for all tree-level primitive QCD amplitudes. The quarks may be massless or massive. We define a generalised cyclic factor $\hat{C}(w…
