CoLoRFulNNLO for hadron collisions: integrating the iterated single unresolved subtraction terms
L. Fekésházy, G. Somogyi, S. Van Thurenhout
We present the analytic integration of the iterated single-unresolved subtraction terms in the extension of the CoLoRFulNNLO subtraction scheme to color-singlet production in hadro…

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…
