A search for tt resonances in lepton+jets events with highly boosted top quarks collected in pp collisions at √s = 7TeV with the ATLAS detector [PDF]

open access: yes, 2012
A search for resonant production of high-mass top-quark pairs is performed on 2.05 fb -1 of proton-proton collisions at √s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider.

Top-Yukawa contributions to bbH production at the LHC

open access: yesJournal of High Energy Physics, 2019
We study the production of a Higgs boson in association with bottom quarks b b ¯ H $$ \left(b\overline{b}H\right) $$ in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa ...

Total cross sections of eγ → eX X ¯ $$ eX\overline{X} $$ processes with X = μ, γ, e via multiloop methods

open access: yesJournal of High Energy Physics, 2021
Using modern multiloop calculation methods, we derive the analytical expressions for the total cross sections of the processes e − γ → e − X X ¯ $$ {e}^{-}X\overline{X} $$ with X = μ, γ or e at arbitrary energies.

Numerical integration of loop integrals through local cancellation of threshold singularities

open access: yesJournal of High Energy Physics, 2022
We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is given by the Loop-Tree Duality integral supplemented with suitable ...

Geometric IR subtraction for final state real radiation

open access: yesJournal of High Energy Physics, 2018
A scheme is proposed for the subtraction of soft and collinear divergences present in massless final state real emission phase space integrals. The scheme is based on a local slicing procedure which utilises the soft and collinear factorisation ...

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}
