Tetrahedral modular graph functions
Axel Kleinschmidt, Valentin Verschinin
The low-energy expansion of one-loop amplitudes in type II string theory generates a series of world-sheet integrals whose integrands can be represented by world-sheet Feynman diag…
The two D6R4 type invariants and their higher order generalisation
Guillaume Bossard, Valentin Verschinin
We show that there are two distinct classes of D6R4 type supersymmetry invariants in maximal supergravity. The second class includes a coupling in F2D4R4 that generalises to 1/8 BP…
type invariants and their gradient expansion
Guillaume Bossard, Valentin Verschinin
We analyse the constraints from supersymmetry on type corrections to the effective action in supergravity in eight dimensions. We prove that there a…
Minimal unitary representations from supersymmetry
Guillaume Bossard, Valentin Verschinin
We compute the supersymmetry constraints on the R^4 type corrections in maximal supergravity in dimension 8, 6, 4 and 3, and determine the tensorial differential equations satisfie…
From Six to Four and More: Massless and Massive Maximal Super Yang-Mills Amplitudes in 6d and 4d and their Hidden Symmetries
Jan Plefka, Theodor Schuster, Valentin Verschinin
A self-consistent exposition of the theory of tree-level superamplitudes of the 4d N=4 and 6d N=(1,1) maximally supersymmetric Yang-Mills theories is provided. In 4d we work in non…
