Asymptotic Weyl Double Copy

Hadi Godazgar, Mahdi Godazgar, Ricardo Monteiro +2

A characteristic value formulation of the Weyl double copy leads to an asymptotic formulation. We find that the Weyl double copy holds asymptotically in cases where the full soluti…

SUSY in the Sky with Gravitons

Gustav Uhre Jakobsen, Gustav Mogull, Jan Plefka +1

Picture yourself in the wave zone of a gravitational scattering event of two massive, spinning compact bodies (black holes, neutron stars or stars). We show that this system of gen…

On the quantisation and anomalies of antisymmetric tensor-spinors

Victor Lekeu, Yi Zhang

We perform the quantisation of antisymmetric tensor-spinors (fermionic -forms) using the Batalin-Vilkovisky field-antifield formalism. Just as for the grav…

Feynman Integrals in Dimensional Regularization and Extensions of Calabi-Yau Motives

Kilian Bönisch, Claude Duhr, Fabian Fischbach +2

We provide a comprehensive summary of concepts from Calabi-Yau motives relevant to the computation of multi-loop Feynman integrals. From this we derive several consequences for mul…

Gauge-invariant theories and higher-degree forms

S. Salgado

A free differential algebra is generalization of a Lie algebra in which the mathematical structure is extended by including of new Maurer-Cartan equations for higher-degree differe…

minimization in presence of hypermultiplets

Antonio Amariti, Alessandra Gnecchi

We compute minimization in gauged supergravity for M-theory and String Theory truncations with both massless and massive vector multiplets. We explicitly compute, as antic…
