Towards regularized higher-order computations in QFT without DREG
German F. R. Sborlini, Felix Driencourt-Mangin, Roger Hernandez-Pinto +1
In this talk, we review the basis of the loop-tree duality theorem, which allows to rewrite loop scattering amplitudes in terms of tree-level like objects. Since the loop measure i…
Mixed QCD-QED corrections to DGLAP equations
German F. R. Sborlini, Daniel de Florian, German Rodrigo
We study the mixed effect of QCD and QED corrections to the evolution of parton distribution functions (PDFs). The Altarelli-Parisi splitting functions are extended to one order hi…
NLO cross sections in 4 dimensions without DREG
R. J. Hernández-Pinto, F. Driencourt-Mangin, G. Rodrigo +1
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 o…
Applications of the loop-tree duality
German Rodrigo, Felix Driencourt-Mangin, German F. R. Sborlini +1
We describe a new method to perform NLO calculations, combining real and virtual amplitudes at the integrand level, with a fully local compensation between them in the IR, and betw…
Four-dimensional unsubtraction with massive particles
German F. R. Sborlini, Felix Driencourt-Mangin, German Rodrigo
We extend the four-dimensional unsubtraction method, which is based on the loop-tree duality (LTD), to deal with processes involving heavy particles. The method allows to perform t…
Attacking One-loop Multi-leg Feynman Integrals with the Loop-Tree Duality
Grigorios Chachamis, Sebastian Buchta, Petros Draggiotis +1
We discuss briefly the first numerical implementation of the Loop-Tree Duality (LTD) method. We apply the LTD method in order to calculate ultraviolet and infrared finite multi-leg…
