Graphical Functions by Examples
Mrigankamauli Chakraborty, Marco Klann, Sven-Olaf Moch +4
Graphical functions have emerged as a powerful framework for evaluating multi-loop Feynman integrals in perturbative quantum field theory. Defined as massless three-point position-…
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…
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…
NNLOCAL: completely local subtractions for color-singlet production in hadron collisions
V. Del Duca, C. Duhr, L. Fekésházy +5
We present NNLOCAL, a proof-of-concept parton-level Monte Carlo program implementing the extension of the completely local subtraction scheme CoLoRFulNNLO to the case of color-sing…
