Gauge-Invariant Double-Copies via Recursion
Jacob L. Bourjaily, Nikhil Kalyanapuram, Kokkimidis Patatoukos +2
We prove that all tree-level amplitudes in pure (super-)gravity can be expressed as term-wise, gauge-invariant double-copies of those of pure (super-)Yang-Mills obtained via BCFW r…
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…
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…
