A scattering amplitudes approach to hard thermal loops
Leonardo de la Cruz
Inspired by recent progress on classical limits of scattering amplitudes, we show that hard thermal loops can be obtained from classical limits of off-shell currents. The classical…
Feynman integrals as A-hypergeometric functions
Leonardo de la Cruz
We show that the Lee-Pomeransky parametric representation of Feynman integrals can be understood as a solution of a certain Gel'fand-Kapranov-Zelevinsky (GKZ) system. In order to d…
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,…
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…
