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.
