TL;DR: In this paper, a direct decomposition of Feynman integrals onto a basis of master integrals on maximal cuts using intersection numbers is presented, where the decomposition formulae computed through the use of intersection numbers are directly verified to agree with the ones obtained using integration-by-parts identities.

TL;DR: In this paper, the authors calculate at high-precision the expansions in e=(4-D)/2 of the master integrals of 4-loop vacuum bubble diagrams with equal masses using a method based on the solution of systems of difference equations.

TL;DR: In this article, the authors connect the direct decomposition of Feynman integrals with the intersection theory, and consider few maximally cut integrals and show their decomposition to the Master Integrals.

TL;DR: In this article, the current status of the theory predictions for elastic $mu$-$e$ scattering is reviewed, describing the recent activities and future plans related to the proposed MUonE experiment.
