Collision geometry in UPC dijet production
Kari J. Eskola, Vadim Guzey, Ilkka Helenius +2
We present a comprehensive NLO pQCD study on inclusive dijet photoproduction in ultraperipheral nucleus-nucleus collisions (UPCs). Our analysis takes into account the finite size o…
Nuclear suppression of coherent photoproduction in heavy-ion UPCs and leading twist nuclear shadowing
V. Guzey, M. Strikman
We determine the nuclear suppression factor , where with the mass and the photon-nucleon energy, for the cross section of…
Spatial resolution of dijet photoproduction in near-encounter ultraperipheral nuclear collisions
Kari J. Eskola, Vadim Guzey, Ilkka Helenius +2
We present next-to-leading order perturbative QCD predictions for inclusive dijet photoproduction in ultra-peripheral nucleus-nucleus collisions (UPCs) within the impact-parameter…
Inclusive and diffractive dijet photoproduction in ultraperipheral Pb-Pb collisions at the LHC
V. Guzey
In this contribution, we summarize NLO pQCD predictions for inclusive and diffractive dijet photoproduction in Pb-Pb UPCs at the LHC. We demonstrate that the theory describes well…
Suppression of diffraction in deep-inelastic scattering on nuclei and dynamical mechanism of leading twist nuclear shadowing
V. Guzey, M. Strikman
Using the leading twist approach (LTA) to nuclear shadowing, we calculate the ratios of diffractive and usual parton distributions for a heavy nucleus (Pb) and the proton, $R_{A/p}…
Slicing Pomerons in ultraperipheral collisions using forward neutrons from nuclear breakup
M. Alvioli, V. Guzey, M. Strikman
We argue that measurements of forward neutrons from nuclear breakup in inclusive high energy photon-nucleus () scattering provide a novel way to study small- dynamics of QCD…
