Infrared factorization of tree-level QCD amplitudes at the next-to-next-to-leading order and beyond
S. Catani, M. Grazzini
We study the infrared behaviour of tree-level QCD amplitudes and we derive infrared-factorization formulae that are valid at any perturbative order. We explicitly compute all the u…
Steps towards NNLO QCD calculations: collinear factorization at O(α_S^2)
M. Grazzini
I consider the singular behaviour of tree-level QCD amplitudes when the momenta of three partons become simultaneously parallel and I discuss the universal factorization formula th…
Target Fragmentation in Semi-Inclusive DIS: Fracture Functions, Cut Vertices and the OPE
M. Grazzini, G. M. Shore, B. E. White
We discuss semi-inclusive Deep Inelastic Scattering (DIS) in the z -> 1 limit, in particular the relationship between fracture functions, generalised cut vertices and Green functio…
Higgs production with large transverse momentum in hadronic collisions at next-to-leading order
D. de Florian, M. Grazzini, Z. Kunszt
Inclusive associated production of a light Higgs boson (m_H < m_t) with one jet in pp collisions is studied in next-to-leading order QCD. Transverse momentum (p_T < 30 GeV) and rap…
