We report on EPPS16 - the first analysis of NLO nuclear PDFs where LHC p-Pb data (Z, W, dijets) have been directly used as a constraint. In comparison to our previous fit EPS09, also data from neutrino-nucleus deeply-inelastic scattering and pion-nucleus Drell-Yan process are now included. Much of the theory framework has also been updated from EPS09, including a consistent treatment of heavy quarks in deeply-inelastic scattering. However, the most notable change is that we no longer assume flavour-blind nuclear modifications for valence and sea quarks. This significantly reduces the theoretical bias. All the analysed data are well reproduced and the analysis thereby supports the validity of collinear factorization in high-energy collisions involving heavy nuclei. However, flavour by flavour, the uncertainties are still rather large.

Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO
Walt, Marina; Helenius, Ilkka; Vogelsang, Werner (American Physical Society, 2019)We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order and next-to-next-to-leading order. Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino ... -
Applicability of pion–nucleus Drell–Yan data in global analysis of nuclear parton distribution functions
Paakkinen, Petja; Eskola, Kari; Paukkunen, Hannu (Elsevier B.V., 2017)Despite the success of modern nuclear parton distribution functions (nPDFs) in describing nuclear hard-process data, they still suffer from large uncertainties. One of the poorly constrained features is the possible asymmetry ... -
Investigation of the elastic and inelastic scattering of 4He from 11B in the energy range 29-50.5 MeV
Burtebayev, N.; Kerimkulov, Zh.; Bakhtybayev, M.; Hamada, Sh.; Mukhamejanov, Y.; Nassurlla, M.; Alimov, D.; Morzabayev, A.; Janseitov, D.; Trzaska, Wladyslaw (IOP Publishing, 2018)We have measured the angular distributions for the elastic and inelastic scattering of 4He from 11B in the isochronous cyclotron U-150 M INP RK. The extracted α-particles beam has been accelerated to energy 29 MeV and then ... -
Interweaving of elementary modes of excitation in superfluid nuclei through particle-vibration coupling: Quantitative account of the variety of nuclear structure observables
Idini, Andrea; Potel, G.; Barranco, F.; Vigezzi, E.; Broglia, R. A. (American Physical Society, 2015)A complete characterization of the structure of nuclei can be obtained by combining information arising from inelastic scattering, Coulomb excitation, and γ -decay, together with one- and two-particle transfer reactions. ... -
Examination of the influence of transfer channels on the barrier height distribution: Scattering of 20Ne on 58Ni, 60Ni, and 61Ni at near-barrier energies
Trzcińska, A.; Piasecki, E.; Amar, A.; Czarnacki, W.; Keeley, N.; Kisieliński, M.; Kliczewski, S.; Kowalczyk, M.; Lommel, B.; Mutterer, M.; Siudak, R.; Stolarz, A.; Strojek, I.; Tyurin, Grigory; Trzaska, Wladyslaw (American Physical Society, 2016)Background: It was suggested that the shape of the barrier height distribution can be determined not only by strong reaction channels (collective excitations) but also by weak channels such as transfers and/or ...
