摘要

The perturbative expansion of two-point functions of lowest dimension supersymmetric operators in N \( \mathcal{N} \) = 4 SYM and ABJM theory exhibits uniform transcendental weight. Inspired by this, we construct an explicit basis of uniformly transcendental master integrals for these correlators, through four loops in four and three loops in three dimensions. In terms of these bases, the two-point functions simplify to rational linear combinations. Conversely, such explicit bases of uniformly transcendental integrals can be useful for other applications.
