1. All-Loop Singularities of Scattering Amplitudes in Massless Planar Theories / Prlina, Igor ; Spradlin, Marcus ; Stanojevic, Stefan
In massless quantum field theories the Landau equations are invariant under graph operations familiar from the theory of electrical circuits. [...]

2. Elliptic Double-Box Integrals: Massless Scattering Amplitudes beyond Polylogarithms / Bourjaily, Jacob L. ; McLeod, Andrew J. ; Spradlin, Marcus ; von Hippel, Matt ; et al
We derive an analytic representation of the ten-particle, two-loop double-box integral as an elliptic integral over weight-three polylogarithms. [...]

3. Correlators in the N = 2 $$ \mathcal{N}=2 $$ supersymmetric SYK model / Peng, Cheng ; Spradlin, Marcus ; Volovich, Anastasia

4. Cluster functions and scattering amplitudes for six and seven points / Harrington, Thomas ; Spradlin, Marcus
Scattering amplitudes in planar super-Yang-Mills theory satisfy several basic physical and mathematical constraints, including physical constraints on their branch cut structure and various empirically discovered connections to the mathematics of cluster algebras. [...]

5. A supersymmetric SYK-like tensor model / Peng, Cheng ; Spradlin, Marcus ; Volovich, Anastasia
We consider a supersymmetric SYK-like model without quenched disorder that is built by coupling two kinds of fermionic N = 1 $$ \mathcal{N}=1 $$ tensor-valued superfields, “quarks” and “mesons”. [...]

6. Heptagons from the Steinmann cluster bootstrap / Dixon, Lance ; Drummond, James ; Harrington, Thomas ; McLeod, Andrew ; et al
We reformulate the heptagon cluster bootstrap to take advantage of the Steinmann relations, which require certain double discontinuities of any amplitude to vanish. [...]

7. Landau singularities and symbology: one- and two-loop MHV amplitudes in SYM theory / Dennen, Tristan ; Spradlin, Marcus ; Volovich, Anastasia
We apply the Landau equations, whose solutions parameterize the locus of possible branch points, to the one- and two-loop Feynman integrals relevant to MHV amplitudes in planar N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills theory. [...]
