We make predictions for the cross sections of coherent photoproduction of ρ, ϕ, J/ψ, ψ (2 S),
and Υ (1 S) mesons in Pb-Pb ultraperipheral collisions (UPCs) at s NN= 5.02 TeV in the …

A bstract We present the calculation of the impact factor for the\({\gamma}^{\left (\ast\right)}\to
q\overline {q}\) transition with one loop accuracy in arbitrary kinematics. The calculation was …

A bstract We make predictions for the cross sections of diffractive dijet photoproduction in pp,
pA and AA ultraperipheral collisions (UPCs) at the LHC during Runs 1 and 2 using next-to …

At high enough energies, QCD processes can be factorized into a hard part, which can be
computed by using the smallness of the strong coupling to apply the perturbative Feynman …

Interactions among heavy ions at the CERN LHC collider recreate the state of matter as it
was a few micro-seconds after the Big Bang: the Quark Gluon Coloured World (QGCW). At a …

Vector meson production in ultra-peripheral pA and AA collisions at the CERN Large
Hadron Collider (LHC) are very sensitive to Parton Distribution Functions (PDF) as well as to …
