$eta_c$ photoproduction at LHC energies

In this contribution, we study the inclusive and diffractive $eta_{c}$ photoproduction in $pp$ and $pPb$ ultra-peripheral collisions (UPCs) at the LHC Run 2 energies. The quarkonium production is studied using nonrelativistic quantum chromodynamics (NRQCD) formalism. We present predictions for rapidity and transverse momentum distributions for the $eta_c$ photoproduction and present our estimate for the total cross sections at the Run 2 energies.
