Color Confinement and Supersymmetric Properties of Hadron Physics from Light-Front Holography
Stanley J. Brodsky
I review applications of superconformal algebra. light-front holography, and an extended form of conformal symmetry to hadron spectroscopy and dynamics. QCD is not supersymmetrical…
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…
From Boundary Data to Bound States II: Scattering Angle to Dynamical Invariants (with Twist)
Gregor Kälin, Rafael A. Porto
We recently introduced in [1910.03008] a "boundary-to-bound" dictionary between gravitational scattering data and observables for bound states of non-spinning bodies. In this paper…
All-Multiplicity Non-Planar MHV Amplitudes in sYM at Two Loops
Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer +2
We give a closed-form, prescriptive representation of all-multiplicity two-loop MHV amplitude integrands in fully-color-dressed (non-planar) maximally supersymmetric Yang-Mills the…
Prescriptive Unitarity for Non-Planar Six-Particle Amplitudes at Two Loops
Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer +2
We extend the applications of prescriptive unitarity beyond the planar limit to provide local, polylogarithmic, integrand-level representations of six-particle MHV scattering ampli…
