Beyond Reggeization for two- and three-loop QCD amplitudes
Vittorio Del Duca, Giulio Falcioni, Lorenzo Magnea +1
The high-energy factorization of gauge theory scattering amplitudes in terms of universal impact factors and a Reggeized exchange in the -channel, corresponding to a Regge pole…
High-energy QCD amplitudes at two loops and beyond
Vittorio Del Duca, Giulio Falcioni, Lorenzo Magnea +1
Recent progress in our understanding of infrared singularities of multi-parton amplitudes has shown that the simplest form of Regge factorization for high-energy gauge-theory ampli…
Integration of collinear-type doubly unresolved counterterms in NNLO jet cross sections
Vittorio Del Duca, Gabor Somogyi, Zoltan Trocsanyi
In the context of a subtraction method for jet cross sections at NNLO accuracy in the strong coupling, we perform the integration over the two-particle factorised phase space of th…
