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…
LinApart2: efficient parallel partial fraction decomposition algorithm for denominators with polynomials of general degree
Levente Fekésházy, Oliver Schnetz
We present LinApart2, a major update to the LinApart algorithm for univariate partial fraction decomposition. Unlike its predecessor, LinApart2 can handle denominators of arbitrary…
Master integrals for semi-inclusive cuts of massless four-loop propagators
Vitaly Magerya, Levente Fekésházy
We present the analytic calculation of all master integrals for 3-, 4-, and 5-particle semi-inclusive cuts of four-loop massless propagators by means of differential equations. We…
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…
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…
