Nuclear parton distributions and nuclear shadowing
Petja Paakkinen, Vadim Guzey
In this contribution, we review the physics and phenomenology of nuclear parton distribution functions (PDFs), with a particular focus on the small-x region of nuclear shadowing. W…
VALO1.0: New real-photon parton distributions with Monte Carlo uncertainties
Madhav Chithirasreemadam, Vadim Guzey, Felix Hekhorn +2
Performing a global QCD analysis of data on the photon structure function in scattering, we determine new leading order (LO) and next-to-leading (NLO) parton…
Dijet photoproduction and transverse-plane geometry in ultra-peripheral nucleus-nucleus collisions
Kari J. Eskola, Vadim Guzey, Ilkka Helenius +2
We present new NLO pQCD predictions for the inclusive photoproduction of dijets in ultra-peripheral (UPC) lead-lead collisions at 5.02 TeV with a realistic impact-parameter depende…
Global fits of proton PDFs with non-linear corrections from gluon recombination
Pit Duwentäster, Vadim Guzey, Ilkka Helenius +1
We present numerical studies of the leading non-linear corrections to the DGLAP evolution equations of parton distribution functions (PDFs) resulting from gluon recombination, whic…
