We present LinApart3, an efficient multivariate partial fraction decomposition algorithm for rational functions with linear denominators. Our decomposition algorithm guarantees tha…
CoLoRFulNNLO for color-singlet processes: An update on NNLOCAL
S. Van Thurenhout, V. Del Duca, C. Duhr +5
We give an update on the status of NNLOCAL, a parton-level Monte Carlo program implementing the extension of the completely local subtraction scheme CoLoRFulNNLO to color-singlet p…
NNLOCAL: Fully Local Subtractions for Precision Predictions in Hadron Collisions
Vittorio Del Duca, Claude Duhr, Levente Fekésházy +5
This work extends the CoLoRFulNNLO subtraction method to address soft and collinear divergences in the computation of higher-order corrections for hadronic collisions. By utilizing…
NNLOCAL: Completely Local Subtractions
Vittorio Del Duca, Claude Duhr, Levente Fekésházy +5
The computation of higher-order corrections to cross sections relevant at LHC involves the evaluation of phase-space integrals that exhibit soft and collinear divergences. The subt…
CoLoRFulNNLO for hadron collisions: integrating the iterated single unresolved subtraction terms

CoLoRFul for hadron collisions: Integrating the counterterms
S. Van Thurenhout, V. Del Duca, C. Duhr +5
In order to numerically compute scattering cross sections in QCD, one needs to deal with various kinematic divergences that appear at intermediate stages of the calculation. One wa…
LinApart: optimizing the univariate partial fraction decomposition
Bakar Chargeishvili, Levente Fekésházy, Gábor Somogyi +1
We present LinApart, a routine designed for efficiently performing the univariate partial fraction decomposition of large symbolic expressions. Our method is based on an explicit c…
