Two-loop SYM Amplitudes via SUSY Decomposition and Massive Spinor-Helicity
Henrik Johansson, Gregor Kälin, Gustav Mogull +1
We obtain a color-kinematics-dual representation of the two-loop four-vector amplitude a general renormalizable massless SYM theory, including internal matter as ch…
Modular graph forms from equivariant iterated Eisenstein integrals
Daniele Dorigoni, Mehregan Doroudiani, Joshua Drewitt +5
The low-energy expansion of closed-string scattering amplitudes at genus one introduces infinite families of non-holomorphic modular forms called modular graph forms. Their differe…
Elliptic modular graph forms II: Iterated integrals
Martijn Hidding, Oliver Schlotterer, Bram Verbeek
Elliptic modular graph forms (eMGFs) are non-holomorphic modular forms depending on a modular parameter of a torus and marked points thereon. Traditionally, eMGFs are const…
Towards closed strings as single-valued open strings at genus one
Jan E. Gerken, Axel Kleinschmidt, Carlos R. Mafra +2
We relate the low-energy expansions of world-sheet integrals in genus-one amplitudes of open- and closed-string states. The respective expansion coefficients are elliptic multiple…
All-order amplitudes at any multiplicity in the multi-Regge limit
V. Del Duca, S. Druc, J. M. Drummond +5
We propose an all-loop expression for scattering amplitudes in planar N=4 super Yang-Mills theory in multi-Regge kinematics valid for all multiplicities, all helicity configuration…
Infrared and transcendental structure of two-loop supersymmetric QCD amplitudes
Gregor Kälin, Gustav Mogull, Alexander Ochirov +1
Using a careful choice of infrared (IR) subtraction scheme, we demonstrate the cancellation of all terms with transcendental weights 0,1,2 from the finite part of the full-color tw…
The Full-Color Two-Loop Four-Gluon Amplitude in Super-QCD
Claude Duhr, Henrik Johansson, Gregor Kälin +2
We present the fully integrated form of the two-loop four-gluon amplitude in supersymmetric quantum chromodynamics with gauge group SU and with massl…
Amplitudes in the Multi-Regge Limit of N=4 SYM
Vittorio Del Duca, Stefan Druc, James Drummond +5
A novel way of computing high-order amplitudes in the multi-Regge limit of planar maximally supersymmetric Yang-Mills theory is presented. In this framework, we are able to obtain…
The Multi-Regge Limit of the Eight-Particle Amplitude Beyond Leading Logarithmic Accuracy
Robin Marzucca, Bram Verbeek
We present the computation of the eight-particle three-loop amplitude beyond leading logarithmic accuracy in the multi-Regge limit of planar N=4 Super Yang-Mills theory. Starting f…
Multi-Loop Amplitudes in the High-Energy Limit in N=4 SYM
Vittorio Del Duca, Stefan Druc, James Drummond +5
We introduce a novel way to perform high-order computations in multi-Regge-kinematics in planar N=4 supersymmetric Yang-Mills theory and generalize the existing factorization into…
The seven-gluon amplitude in multi-Regge kinematics beyond leading logarithmic accuracy
Vittorio Del Duca, Stefan Druc, James Drummond +5
We present an all-loop dispersion integral, well-defined to arbitrary logarithmic accuracy, describing the multi-Regge limit of the 2->5 amplitude in planar N=4 super Yang-Mills th…
The analytic structure and the transcendental weight of the BFKL ladder at NLL accuracy
Vittorio Del Duca, Claude Duhr, Robin Marzucca +1
We study some analytic properties of the BFKL ladder at next-to-leading logarithmic accuracy (NLLA). We use a procedure by Chirilli and Kovchegov to construct the NLO eigenfunction…
Multi-Regge kinematics and the moduli space of Riemann spheres with marked points
Vittorio Del Duca, Stefan Druc, James Drummond +5
We show that scattering amplitudes in planar N = 4 Super Yang-Mills in multi-Regge kinematics can naturally be expressed in terms of single-valued iterated integrals on the moduli…
