A bstract We compute three families of two-loop six-point massless Feynman integrals in
dimensional regularization, namely the double-box, the pentagon-triangle, and the hegaxon …

A bstract We consider the complete set of planar two-loop five-point Feynman integrals with
two off-shell external legs. These integrals are relevant, for instance, for the calculation of the …

We reformulate the Landau analysis of Feynman integrals with the aim of advancing the
state of the art in modern particle-physics computations. We contribute new algorithms for …

A bstract Parametric representations of Feynman integrals have a key property: many,
frequently all, of the Landau singularities appear as endpoint divergences. This leads to a …

We present an algorithm for determining the minimal order differential equations associated
with a given Feynman integral in dimensional or analytic regularisation. The algorithm is an …

A bstract A recent evaluation of three-loop nonplanar Feynman integrals contributing to
Higgs plus jet production has established their dependence on two novel symbol letters. We …

A bstract The method of regions, which provides a systematic approach for computing
Feynman integrals involving multiple kinematic scales, proposes that a Feynman integral …

A bstract We consider the 5-mass kite family of self-energy Feynman integrals and present a
systematic approach for constructing an ε-form basis, along with its differential equation …

A powerful approach to computing Feynman integrals or cosmological correlators is to
consider them as solution to systems of differential equations. Often these can be chosen to …

We derive the full system of canonical differential equations for all planar two-loop massless
six-particle master integrals, and determine analytically the boundary conditions. This fully …
