PDF evolution in alternative factorisation schemes
Stéphane Delorme, Aleksander Kusina, Andrzej Siódmok +1
Beyond leading order, parton distribution functions (PDFs) require a choice of factorisation scheme to be defined unambiguously. Different choices of factorisation scheme lead to P…
KrkNLO matching and phenomenology for vector boson processes
Pratixan Sarmah, Andrzej Siódmok, James Whitehead
The combination of NLO matrix elements with parton showers is indispensable for LHC physics. Differences between matching methods introduce matching uncertainties, corresponding to…
Factorisation schemes for proton PDFs
Stéphane Delorme, Aleksander Kusina, Andrzej Siódmok +1
Beyond leading-order, perturbative QCD requires a choice of factorisation scheme to define the parton distribution functions (PDFs) and hard-process cross-section. The modified min…
KrkNLO matching for colour-singlet processes
Pratixan Sarmah, Andrzej Siódmok, James Whitehead
Matched calculations combining perturbative QCD with parton showers are an indispensable tool for LHC physics. Two methods for NLO matching are in widespread use: MC@NLO and POWHEG…
