Additional results on the four-loop flavour-singlet splitting functions in QCD
G. Falcioni, F. Herzog, S. Moch +2
We have extended our previous computations, performed analytically for a general gauge group, of the even- moments $γ_{\rm ik}^{\,(3)}(N)$ of the four-loop flavour-singlet spli…
Alien operators for PDF evolution
S. Van Thurenhout, G. Falcioni, F. Herzog +1
Understanding the scale dependence of parton distribution functions is vital for precision physics at hadron colliders. The well-known DGLAP evolution equation relates this scale d…
The two-loop Higgs impact factor
Vittorio Del Duca, Giulio Falcioni
In the HEFT, we consider the Regge limit of the two-loop amplitudes for Higgs boson production in association with a jet, expanded to NNLL accuracy. We discuss the issue of the Reg…
The Two-Loop Lipatov Vertex in QCD
Samuel Abreu, Giuseppe De Laurentis, Giulio Falcioni +3
High-energy factorization of 2 -> 2 amplitudes in QCD has been recently pushed to the next-to-next-to-leading logarithmic order by determining the three-loop gluon Regge trajectory…
Regge poles and cuts and the Lipatov vertex
Samuel Abreu, Giulio Falcioni, Einan Gardi +2
Scattering amplitudes in the high-energy limit can be described in terms of their singularity structure in the complex angular momentum plane, consisting of Regge poles and cuts. I…
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…
