Abstract
The Precision Proton Spectrometer (PPS) started operating in 2016 and has collected more than 110 fb$^{-1}$ of data over the course of the LHC Run 2, now fully available for physics analysis. This contribution covers the key features of the PPS alignment and optics calibration, which have been developed from scratch. The reconstructed proton distributions, the performance of the PPS simulation and finally the validation of the full reconstruction chain with physics data (dilepton events) are also illustrated.

Report
Precision Proton Spectrometer (PPS) was installed in 2016 and was integrated with CMS during the LHC Run 2. Physics motivation behind the PPS detector is the study of central exclusive production (CEP) pp → p(∗) + X + p(∗) mediated by color-singlet exchanges (photons, Pomerons, Z bosons), with at least one of the outgoing protons detected in PPS. Resolution od the detector and upgrade for Run-3. It is expected the detector would work better with the upgrade. It is nicely written and I would recommend this work for publication.
