Revisiting inclusive production of J/psi and Upsilon in high-energy gamma-gamma collisions
Yelyzaveta Yedelkina, Jean-Philippe Lansberg, Maxim Nefedov
The impact of Next-to-Leading Order (NLO) QCD corrections to the differential distributions of J/psi and Upsilon mesons produced inclusively in gamma-gamma collisions is discussed…

On the high-energy instability of quarkonium production
Maxim Nefedov
The perturbative instability of NLO collinear factorisation (CF) computations of -integrated cross sections of heavy quarkonium production at high hadronic or photon-hadron co…

Curing the high-energy perturbative instability of vector-quarkonium-photoproduction cross sections at order with high-energy factorisation
Jean-Philippe Lansberg, Maxim Nefedov, Melih A. Ozcelik
We cure the perturbative instability of the total-inclusive-photoproduction cross sections of vector -wave quarkonia observed at high photon-proton-collision energies ($\sqrt{s_…
