NLO cross sections in 4 dimensions without DREG
Abstract
In this review, we present a new method for computing physical cross sections at NLO accuracy in QCD without using the standard Dimensional Regularisation. The algorithm is based on the Loop-Tree Duality theorem, which allow us to obtain loop integrals as a sum of phase-space integrals; in this way, transforming loop integrals into phase-space integrals, we propose a method to merge virtual and real contributions in order to find observables at NLO in space-time dimensions. In addition, the strategy described is used for computing the process. A more detailed discussion related on this topic can be found in Ref [1].
