Cluster algebras for Feynman integrals
Dmitry Chicherin, Johannes M. Henn, Georgios Papathanasiou
We initiate the study of cluster algebras in Feynman integrals in dimensional regularization. We provide evidence that four-point Feynman integrals with one off-shell leg are descr…
Conformal anomaly of pseudo-scalar operators
Dmitry Chicherin, Emery Sokatchev
We study the conformal properties of pseudo-scalar (parity-odd) operators in four-dimensional field theory. Such operators include the topological term in a gauge theory and the Yu…
Multi-Regge Limit of the Two-Loop Five-Point Amplitudes in Super Yang-Mills and Supergravity
Simon Caron-Huot, Dmitry Chicherin, Johannes Henn +2
In previous work, the two-loop five-point amplitudes in super Yang-Mills theory and supergravity were computed at symbol level. In this paper, we co…
From correlation functions to event shapes in QCD
D. Chicherin, J. M. Henn, E. Sokatchev +1
We present a method for calculating event shapes in QCD based on correlation functions of conserved currents. The method has been previously applied to the maximally supersymmetric…
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…
