Complete construction of magical, symmetric and homogeneous N=2 supergravities as double copies of gauge theories
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
We show that scattering amplitudes in magical, symmetric or homogeneous N=2 Maxwell-Einstein supergravities can be obtained as double copies of two gauge theories, using the framew…
Spontaneously Broken Yang-Mills-Einstein Supergravities as Double Copies
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
Color/kinematics duality and the double-copy construction have proved to be systematic tools for gaining new insight into gravitational theories. Extending our earlier work, in thi…
Color-Kinematics Duality for QCD Amplitudes
Henrik Johansson, Alexander Ochirov
We show that color-kinematics duality is present in tree-level amplitudes of quantum chromodynamics with massive flavored quarks. Starting with the color structure of QCD, we work…
Cross-Order Integral Relations from Maximal Cuts
Henrik Johansson, David A. Kosower, Kasper J. Larsen +1
We study the ABDK relation using maximal cuts of one- and two-loop integrals with up to five external legs. We show how to find a special combination of integrals that allows the r…
