Integrands of Less-Supersymmetric Yang-Mills at One Loop
Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer +3
We construct a prescriptive, bubble power-counting basis of one-loop integrands suitable for representing amplitude integrands in less-supersymmetric Yang-Mills theory. With the ex…
Illustrations of Integrand-Basis Building at Two Loops
Jacob L. Bourjaily, Cameron Langer, Yaqi Zhang
We outline the concrete steps involved in building prescriptive master integrand bases for scattering amplitudes beyond the planar limit. We highlight the role of contour choices i…
All Two-Loop, Color-Dressed, Six-Point Amplitude Integrands in sYM
Jacob L. Bourjaily, Cameron Langer, Yaqi Zhang
We construct all six-particle helicity amplitude integrands in color-dressed, maximally supersymmetric Yang-Mills theory at two loops in a single prescriptive basis of master integ…
Locally Finite Observables in sYM
Jacob L. Bourjaily, Cameron Langer, Kokkimidis Patatoukos
A `locally-finite' observable is one for which there is no region of divergence anywhere in the space of real loop momenta; it can therefore be computed (in principle) without regu…
Prescriptive Unitarity with Elliptic Leading Singularities
Jacob L. Bourjaily, Nikhil Kalyanapuram, Cameron Langer +1
We investigate the consequences of elliptic leading singularities for the unitarity-based representations of two-loop amplitudes in planar, maximally supersymmetric Yang-Mills theo…
An Elliptic Yangian-Invariant, `Leading Singularity'
Jacob L. Bourjaily, Nikhil Kalyanapuram, Cameron Langer +2
We derive closed formulae for the first examples of non-algebraic, elliptic `leading singularities' in planar, maximally supersymmetric Yang-Mills theory and show that they are Yan…
