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…
Anomalous dimensions for exclusive processes
S. Van Thurenhout
We give an overview of recent developments in the computation of the anomalous dimension matrix of composite operators in non-forward kinematics. The elements of this matrix set th…
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…
Basis transformation properties of anomalous dimensions for hard exclusive processes
S. Van Thurenhout
When considering the renormalization of composite operators for the description of hard exclusive scattering processes, two types of operator basis called the derivative basis and…
Constraints for twist-two alien operators in QCD
G. Falcioni, F. Herzog, S. Moch +1
Parton evolution equations in QCD are controlled by the anomalous dimensions of gauge-invariant twist-two spin- quark and gluon operators. Under renormalization, these mix with…
