Improving colour computations in MadGraph5_aMC@NLO and exploring a $$1/N_c$$ expansion [PDF]

open access: yesThe European Physical Journal C, 2022
AbstractIn this paper, we present an extension of which is able to evaluate tree-level QCD matrix-elements up to $$2\rightarrow 6$$ 2 → 6 (one more particle than before).

A tool for automated perturbative cross section computations of asymmetric hadronic collisions at next-to-leading order using the $\texttt{MadGraph5_aMC@NLO}$ framework [PDF]

open access: yes, 2022
International audienceAutomated perturbative computations of cross sections for hard processes in asymmetric hadronic collisions at next-to-leading order in $\alpha_s$ will offer a wide range of applications, such as more robust predictions for new ...

The partonic structure of the electron at the next-to-leading logarithmic accuracy in QED

open access: yesJournal of High Energy Physics, 2020
By working in QED, we obtain the electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron at the next-to-leading logarithmic accuracy.

Two-loop master integrals for the leading QCD corrections to the Higgs coupling to a W pair and to the triple gauge couplings ZW W and γ∗ W W

open access: yesJournal of High Energy Physics, 2017
We compute the two-loop master integrals required for the leading QCD corrections to the interaction vertex of a massive neutral boson X 0, e.g. H, Z or γ∗, with a pair of W bosons, mediated by a SU(2) L quark doublet composed of one massive and one ...

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at √s=7 TeV with the ATLAS detector [PDF]

open access: yes, 2011
The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton–proton collisions at a centre-of-mass energy of √s=7 TeV, using the ATLAS detector at the LHC.

Functional reduction of Feynman integrals

open access: yesJournal of High Energy Physics, 2019
A method for reducing Feynman integrals, depending on several kinematic variables and masses, to a combination of integrals with fewer variables is proposed. The method is based on iterative application of functional equations proposed by the author. The

NLO ACTIVITY AND COMPUTATIONAL DISCUSSION OF HALOGEN-SUBSTITUTED CHALCONE DERIVATIVES

open access: yesRASAYAN Journal of Chemistry, 2023
The four halogen-substituted chalcones 1–4 have been synthesized and analyzed to FT-Infrared, UV-Visible, GC-MS spectrometer, and 1D NMR (1H and 13C) spectroscopy techniques. Computational calculations were carried out for geometrical optimization of structure regards bond length, bond angle, and torsional angle estimated.

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at √s=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron ...

Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution

open access: yesJournal of High Energy Physics, 2019
The annihilation cross section of weakly interacting TeV scale dark matter particles χ 0 into photons is affected by large quantum corrections due to electroweak Sudakov logarithms and the Sommerfeld effect. We extend our previous work on the resummation
