Soft gluon emission at two loops in full color
Lance J. Dixon, Enrico Herrmann, Kai Yan +1
The soft emission factor is a central ingredient in the factorization of generic -particle gauge theory amplitudes with one soft gluon in the external state. We present the comp…
The Cosmic Galois Group and Extended Steinmann Relations for Planar SYM Amplitudes
Simon Caron-Huot, Lance J. Dixon, Falko Dulat +3
We describe the minimal space of polylogarithmic functions that is required to express the six-particle amplitude in planar super-Yang-Mills theory through six and sev…
The Collinear Limit of the Energy-Energy Correlator
Lance J. Dixon, Ian Moult, Hua Xing Zhu
The energy-energy-correlator (EEC) observable in annihilation measures the energy deposited in two detectors as a function of the angle between the detectors. The collinea…
Six-Gluon Amplitudes in Planar Super-Yang-Mills Theory at Six and Seven Loops
Simon Caron-Huot, Lance J. Dixon, Falko Dulat +3
We compute the six-particle maximally-helicity-violating (MHV) and next-to-MHV (NMHV) amplitudes in planar maximally supersymmetric Yang-Mills theory through seven loops and six lo…
The two-loop five-point amplitude in supergravity
Samuel Abreu, Lance J. Dixon, Enrico Herrmann +2
We compute the symbol of the two-loop five-point amplitude in supergravity. We write an ansatz for the amplitude whose rational prefactors are based on not only 4-di…
