Descripción
Quantum corrections to physical observables in High Energy Physics are computed by means of perturbative Quantum Field Theory. Within the framework of pertubative QCD, the study of multi loops and legs is becoming crucial to understand the physics of fundamental particles and its interactions. Along the years, several methods have been developed to overcome the ill-defined quantities that appear in any multiloop calculation. In this talk, we review the Four Dimensional Unsubtraction, a new algorithm based on the Loop- Tree Duality theorem to compute accurate theoretical predictions in four space-time dimensions.
