TUJU21: nuclear PDFs with electroweak-boson data at NNLO
Ilkka Helenius, Marina Walt, Werner Vogelsang
Nuclear parton distribution functions (nPDFs) can be determined in a global QCD analysis using a wide range of experimental data. In addition to older fixed-target deep inelastic s…
Spatially dependent parton distribution functions and hard processes in nuclear collisions
Ilkka Helenius
This work focuses on applications of perturbative QCD (pQCD) and collinear factorization theorem to hard particle production in nuclear and hadronic collisions at the BNL-RHIC and…
LHC data challenges the contemporary parton-to-hadron fragmentation functions
David d'Enterria, Kari J. Eskola, Ilkka Helenius +1
We discuss the inclusive high-pT charged-particle production in proton-proton collisions at the LHC. The experimental data are compared to the NLO perturbative QCD calculations emp…
Zeroing in on the initial state -- tomography using bulk, jets and photons
Thorsten Renk, Rupa Chatterjee, Kari J. Eskola +2
One of the unsolved problems in the current 'standard model' of heavy ion physics is the apparent rapid thermalization of QCD matter in the pre-equilibrium stage. While it is chall…
Probing the small- nuclear gluon distributions with isolated photons at forward rapidities in p+Pb collisions at the LHC
Ilkka Helenius, Kari J. Eskola, Hannu Paukkunen
Inclusive direct photon production in p+Pb collisions at the LHC is studied within the NLO perturbative QCD. Our aim is to quantify the dominant regions probed at different rap…
