Abstract

Feasibility studies for the measurement of single-diffractive (SD) Z or W boson, $J/\psi$ meson in the muon decay channel and Central Exclusive (CEP) Dijets production in proton-proton (${\rm pp}$) collisions at $\sqrt{s}=13$~TeV with the Compact Muon Solenoid (CMS) and TOTEM experiments are presented. Visible cross sections for such processes are presented based on the Large Hadron Collider (LHC) Run II beam optics configuration.
