One-loop matrix element emulation with factorisation awareness

In this article we present an emulation strategy for one-loop matrix elements. This is based on the factorisation properties of elements and extension work presented in arXiv:2107.06625. We show that a percent-level accuracy can be achieved even large multiplicity processes. The point obtained such it dwarfs statistical training sample which allows us to use our model augment size set by orders magnitude without additional evaluations expensive
