Results and prospects with the CMS-TOTEM Precision Proton Spectrometer

With more than 100 fb$^{-1}$ recorded during LHC run 2 (2016-2018), the joint CMS-TOTEM Precision Proton Spectrometer (CT-PPS) has started to deliver its first physics results.Located between 200 and 220 m on each side from the CMS detector, it aims the detection of forward scattered protons emerging intact from the interaction, as for instance in central exclusive processes (CEP).In this proceeding we describe in details the search for two-photon production of a lepton pair performed with the first 10 fb$^{-1}$.With this result, it has proved for the first time the feasibility of operating near-beam detectors close to the LHC beams under nominal luminosity conditions.In addition, we describe the potential for future physics prospects in preparation to the run 3 of the LHC.
