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…
The LHC p+Pb run from the nuclear PDF perspective
Hannu Paukkunen
The p+Pb and Pb+Pb runs at the LHC have opened a possibility to investigate the validity of collinear factorization in a clearly higher center-of-mass energy scale than earlier in…
Hessian PDF reweighting meets the Bayesian methods
Hannu Paukkunen, Pia Zurita
We discuss the Hessian PDF reweighting - a technique intended to estimate the effects that new measurements have on a set of PDFs. The method stems straightforwardly from consideri…
Dijets in p+Pb collisions and their quantitative constraints for nuclear PDFs
Hannu Paukkunen, Kari J. Eskola, Carlos Salgado
We present a perturbative QCD analysis concerning the production of high-pT dijets in p+Pb collisions at the LHC. The next-to-leading order corrections, scale variations and free-p…
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…
Constraining nPDFs with inclusive pions and direct photons at forward rapidities in p+Pb collisions at the LHC
Ilkka Helenius, Kari J. Eskola, Hannu Paukkunen
In this talk, we present NLO pQCD predictions for inclusive pion and direct photon nuclear modifications in p+Pb collisions at mid- and forward rapidities at the LHC. In addition t…
