Next-to-leading-order QCD and electroweak corrections to WWW production at proton-proton colliders

open access: yesJournal of High Energy Physics, 2017
Triple-W-boson production in proton-proton collisions allows for a direct access to the triple and quartic gauge couplings and provides a window to the mechanism of electroweak symmetry breaking. It is an important process to test the Standard Model (SM)

NLO EW and QCD corrections to polarized ZZ production in the four-charged-lepton channel at the LHC

open access: yesJournal of High Energy Physics, 2021
Measuring the polarization of electroweak bosons at the LHC allows for important tests of the electroweak-symmetry-breaking mechanism that is realized in nature.

Off-shell production of top-antitop pairs in the lepton+jets channel at NLO QCD

open access: yesJournal of High Energy Physics, 2018
The production of top-quark pairs that subsequently decay hadronically and leptonically (lepton+jets channel) is one of the key processes for the study of top-quark properties at the LHC. In this article, NLO QCD corrections of order Oαs3α4 $$ \mathcal{O}

Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold

open access: yesJournal of High Energy Physics, 2021
We calculate the generalized soft functions at O $$ \mathcal{O} $$ ( α s 2 $$ {\alpha}_s^2 $$ ) at next-to-leading power accuracy for the Drell-Yan process at threshold.

A Positive-Weight Next-to-Leading-Order Monte Carlo for Heavy Flavour Hadroproduction

open access: yes, 2007
We present a next-to-leading order calculation of heavy flavour production in hadronic collisions that can be interfaced to shower Monte Carlo programs. The calculation is performed in the context of the POWHEG method.

Automation of one-loop QCD corrections [PDF]

open access: yes, 2011
We present the complete automation of the computation of one-loop QCD corrections, including UV renormalization, to an arbitrary scattering process in the Standard Model. This is achieved by embedding the OPP integrand reduction technique, as implemented

Double longitudinal-spin asymmetries in J/ψ production at RHIC

open access: yesJournal of High Energy Physics, 2018
The double longitudinal-spin asymmetry, A LL , of the J/ψ production in polarized proton-proton collisions is presented in this paper at QCD next-to-leading order.

Integrated dipoles with MadDipole in the MadGraph framework [PDF]

open access: yes, 2010
Heading towards a full automation of next-to-leading order (NLO) QCD corrections, one important ingredient is the analytical integration over the one-particle phase space of the unresolved particle that is necessary when adding the subtraction terms to ...
