From Six to Four and More: Massless and Massive Maximal Super Yang-Mills Amplitudes in 6d and 4d and their Hidden Symmetries
Jan Plefka, Theodor Schuster, Valentin Verschinin
A self-consistent exposition of the theory of tree-level superamplitudes of the 4d N=4 and 6d N=(1,1) maximally supersymmetric Yang-Mills theories is provided. In 4d we work in non…
Color ordering in QCD
Theodor Schuster
We derive color decompositions of arbitrary tree and one-loop QCD amplitudes into color ordered objects called primitive amplitudes. Furthermore, we derive general fermion flip and…
Comparing efficient computation methods for massless QCD tree amplitudes: Closed Analytic Formulae versus Berends-Giele Recursion
Simon Badger, Benedikt Biedermann, Lucas Hackl +3
Recent advances in our understanding of tree-level QCD amplitudes in the massless limit exploiting an effective (maximal) supersymmetry have led to the complete analytic constructi…
All tree-level amplitudes in massless QCD
Lance J. Dixon, Johannes M. Henn, Jan Plefka +1
We derive compact analytical formulae for all tree-level color-ordered gauge theory amplitudes involving any number of external gluons and up to three massless quark-anti-quark pai…
Gravitational Corrections to Yukawa and Phi^4 Interactions
Andreas Rodigast, Theodor Schuster
We consider the lowest order quantum gravitational corrections to Yukawa and Phi^4 interactions. Our results show that quantum gravity leads to contributions to the running couplin…
Scattering into the fifth dimension of N=4 super Yang-Mills
Luis F. Alday, Johannes M. Henn, Jan Plefka +1
We study an alternative to dimensional regularisation of planar scattering amplitudes in N=4 super Yang-Mills theory by going to the Coulomb phase of the theory. The infrared diver…
