From Transition Electromagnetic Form Factors $\gamma^* \gamma^* \eta_c(1S,2S)$ to the Production of $\eta_c(1S,2S)$ at the LHC
We review our recent results for production of $\eta_c(1S)$ and $\eta_c(2S)$ in the $\gamma^* \gamma^* \to \eta_c(1S,2S)$ fusion and in proton-proton collisions via gluon-gluon fusion. The quarkonium wave functions are calculated by solving Schr\"odinger equation for different $c \bar c$ potent...
