New parton distribution functions of the real photon
Madhav Chithirasreemadam, Vadim Guzey, Felix Hekhorn +2
Precise determination of the partonic structure of real photons has attracted renewed interest in view of ongoing studies of high-energy photon-induced processes in ultraperipheral…
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…
