| Abstract: A generic search is presented for associated production of a Z boson or a photon with an additional unspecified massive particle X in proton-tagged events from pp collisions at $\sqrt{s} = $ 13 TeV, recorded in 2017 by the CMS detector and the CMS-TOTEM precision proton spectrometer. The so-called missing mass spectrum is analysed in the 600-1600 GeV range and a fit is performed to search for possible deviations from the background expectation. Model-independent upper limits on the visible production cross section of pp $\rightarrow$ pp $+$ Z/$\gamma$ $+$ X are set, in the absence of significant resonant deviations in data with respect to the background predictions. | ||
