Conformal Invariance of the One-Loop All-Plus Helicity Scattering Amplitudes
Johannes Henn, Bláithín Power, Simone Zoia
The massless QCD Lagrangian is conformally invariant and, as a consequence, so are the tree-level scattering amplitudes. However, the implications of this powerful symmetry at loop…

Analytic form of the full two-loop five-gluon all-plus helicity amplitude
S. Badger, D. Chicherin, T. Gehrmann +6
We compute the full-color two-loop five-gluon amplitude for the all-plus helicity configuration. In order to achieve this, we calculate the required master integrals for all permut…

The two-loop five-particle amplitude in supergravity
D. Chicherin, T. Gehrmann, J. M. Henn +3
We compute for the first time the two-loop five-particle amplitude in supergravity. Starting from the known integrand, we perform an integration-by-parts reduction…
