The CMS+TOTEM Precision Proton Spectrometer operated for the first time in 2016, collecting data during pp collisions at √(s) = 13 TeV at the CERN Large Hadron Collider. Procedures for the detector alignment, optics corrections, and background estimations were developed, and applied to an analysis of the process pp → p μ+μ- p(*) with dimuon masses larger than 110 GeV. A total of 12 candidate events are observed, corresponding to an excess of >4σ over the background prediction. This constitutes the first evidence for this process at such masses, and demonstrates the good performance of CT-PPS.
