Higher-orders in heavy quark processes within the LTD approach
German F. R. Sborlini
The computation of perturbative corrections to processes involving heavy quarks is crucial for the precision program of the LHC and future colliders. In this article, we describe a…
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…
Two-loop QED corrections to the Altarelli-Parisi splitting functions
Daniel de Florian, German F. R. Sborlini, German Rodrigo
We compute the two-loop QED corrections to the Altarelli-Parisi (AP) splitting functions by using a deconstructive algorithmic Abelianization of the well-known NLO QCD corrections.…
Four-dimensional unsubtraction from the loop-tree duality
German F. R. Sborlini, Felix Driencourt-Mangin, Roger Hernandez-Pinto +1
We present a new algorithm to construct a purely four dimensional representation of higher-order perturbative corrections to physical cross-sections at next-to-leading order (NLO).…
Loop-tree duality and quantum field theory in four dimensions
German F. R. Sborlini
Loop-tree duality allows to express virtual contributions in terms of phase-space integrals, thus leading to a direct comparison with real radiation terms. In this talk, we review…
