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…

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…
