Searching for gluon saturation effects in the momentum transfer dependence of coherent charmonium electroproduction off nuclei
J. Nemchik, J. Ãbertová
We study for the first time the transverse momentum transfer distributions in coherent production of charmonia in nuclear ultra-peripheral and electron-ion collisions with…

Coherent photo- and electroproduction of charmonia on nuclear targets revisited: Green function formalism
J. Nemchik, J. Ãbertová
We study for the first time the production of charmonia in nuclear ultra-peripheral and electron-ion collisions based on a rigorous Green function formalism. Such formalism allows…

Path integral treatment of coherence effects in charmonium production in nuclear ultra-peripheral collisions
J. Ãbertová, J. Nemchik
We present for the first time a revised study of charmonium production in nuclear ultra-peripheral collisions (UPC) based on a rigorous Green function formalism. This formalism all…
