$\gamma\gamma$ and $\gamma p$ measurements with forward proton taggers in CMS+TOTEM

The CMS+TOTEM Precision Proton Spectrometer operated for the first time in 2016, collecting data during pp collisions at sqrt(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 mu+mu-p(*) with dimuon masses larger than 110 GeV. A total of 12 candidate events are observed, corresponding to an excess of >4 sigma over the background prediction. This constitutes the first evidence for this process at such masses, and demonstrates the good performance of CT-PPS
