Description
In this talk, I will present the computation of the soft gluon emission at two loops. Such a limit is the only remaining unknown necessary for the construction of an N3LO subtraction scheme. Starting from two loops, two types of topologies contribute: the "dipole" which is already known up to the necessary order, and the "tripole", known in the literature up to O($\epsilon^0$). My work aims to be the first confirmation of the available results for the tripole, and its extension to O($\epsilon$).
