Triple collinear splitting functions at NLO for scattering processes with photons
(Springer, 2014-10)
Abstract: We present splitting functions in the triple collinear limit at next-to-leading order. The computation was performed in the context of massless QCD+QED, considering only processes which include at least one photon. ...
Double collinear splitting amplitudes at next-to-leading order
(Springer, 2014-01)
We compute the next-to-leading order (NLO) QCD corrections to the 1 → 2 splitting amplitudes in different dimensional regularization (DREG) schemes. Besides recovering previously known results, we explore new DREG schemes ...
Anomalous couplings in Higgs-boson pair production at approximate NNLO QCD
(Springer, 2021-09-23)
We combine NLO predictions with full top-quark mass dependence with approximate NNLO predictions for Higgs-boson pair production in gluon fusion, including the possibility to vary coupling parameters within a non-linear ...
A next-to-next-to-leading order calculation of soft-virtual cross sections
(Springer, 2012-12)
We compute the next-to-next-to-leading order (NNLO) soft and virtual QCD corrections for the partonic cross section of colourless-final state processes in hadronic collisions. The results are valid to all orders in the ...
Differential Higgs boson pair production at next-to-next-to-leading order in QCD
(Springer, 2016-09)
We report on the first fully differential calculation for double Higgs boson production through gluon fusion in hadron collisions up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. The calculation is ...
Space-like (vs. time-like) collinear limits in QCD: Is factorization violated?
(Springer, 2012-07)
We consider the singular behaviour of QCD scattering amplitudes in kinematical configurations where two or more momenta of the external partons become collinear. At the tree level, this behaviour is known to be controlled ...
Threshold resummation for high-transverse-momentum Higgs production at the LHC
(IOP Publishing, 2006-02)
We study the resummation of large logarithmic QCD corrections for the process pp → H + X when the Higgs boson H is produced at high transverse momentum. The corrections arise near the threshold for partonic reaction and ...
Mixed QCD⊗QED corrections to exclusive Drell Yan production using the qT -subtraction method
(Springer, 2020-09)
In this work we extend the qT -subtraction formalism, originally developed for QCD corrections, to the case of mixed QCD⊗QED corrections, and apply it to the fully exclusive calculation of the O(αsα) contribution to the ...
Triple Higgs production at hadron colliders at NNLO in QCD
(Springer, 2020-03)
In this work we analyse the triple Higgs boson production cross section at hadron colliders via gluon fusion, and present for the first time the full set of QCD NNLO corrections in the heavy top limit. In order to account ...
Hadron plus photon production in polarized hadronic collisions at next-to-leading order accuracy
(American Physical Society, 2011-04)
We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, ...
