A generic search is presented for the associ- ated production of a Z boson or a photon with an addi- tional unspecified massive particle X, pp → pp + Z/γ + X, in proton-tagged events from proton–proton collisions at √s = 13 TeV, recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer. The missing mass spectrum is analysed in the 600–1600 GeV range and a fit is performed to search for possible devia- tions from the background expectation. No significant excess in data with respect to the background predictions has been observed. Model-independent upper limits on the visible pro- duction cross section of pp → pp + Z/γ + X are set.
