Properties of Yang-Mills scattering forms
Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl
In this talk we introduce the properties of scattering forms on the compactified moduli space of Riemann spheres with marked points. These differential forms are $\text{PSL}(2,…
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…
Relations and representations of QCD amplitudes
Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl
In this talk we review relations and representations of primitive QCD tree amplitudes. Topics covered include the BCJ relations, the CHY representation, and the KLT relations. We w…
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…
