Author in the following contributions
- The ${\gamma^* \gamma^* \to \eta_c (1S,2S)}$ transition form factor from quarkonium wave functions
- Production of $W^+ W^-$ and $t \bar t$ pairs via photon-photon processes in proton-proton scattering and corresponding gap survival factor
- Production of $\chi_c(i) \chi_c(j)$ pairs in proton-proton collisions in $k_t$-factorization and collinear approaches
