A QCD analysis for nuclear PDFs at NNLO
Marina Walt, Ilkka Helenius, Werner Vogelsang
A new QCD analysis for nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) is presented. The framework of the anal…
Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO
Marina Walt, Ilkka Helenius, Werner Vogelsang
We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). Our analyses are based on deeply inela…
Double D-meson production in proton-proton and proton-lead collisions at the LHC
Ilkka Helenius, Hannu Paukkunen
We consider the simultaneous production of two heavy-flavoured hadrons - particularly D mesons - at the LHC. We base our calculations on collinearly factorized QCD at next-to-leadi…
Constraints for nuclear PDFs from the LHCb D-meson data
Kari J. Eskola, Ilkka Helenius, Petja Paakkinen +1
We quantify the impact of LHCb D-meson measurements at on the EPPS16 and nCTEQ15 nuclear PDFs. In our study, the theoretical description of D-meson produc…
A QCD analysis of LHCb D-meson data in p+Pb collisions
Kari J. Eskola, Ilkka Helenius, Petja Paakkinen +1
We scrutinize the recent LHCb data for D-meson production in p+Pb collisions within a next-to-leading order QCD framework. Our calculations are performed in the SACOT-$m_{\rm T…
Hadroproduction of open heavy flavour for PDF analyses
Ilkka Helenius, Hannu Paukkunen
Due to the large masses of the charm and bottom quarks, their production cross sections are calculable within the perturbative QCD. This makes the heavy-quark mesons important obse…
