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

The 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).

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

Journal 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

Journal 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]

, 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.

Relic density computations at NLO: infrared finiteness and thermal correction [PDF]

Journal of High Energy Physics, 2014
Abstract There is an increasing interest in accurate dark matter relic density predictions, which requires next-to-leading order (NLO) calculations. The method applied up to now uses zero-temperature NLO calculations of annihilation cross sections in the standard Boltzmann equation for freeze-out, and is conceptually ...
