A search for new physics in central exclusive production using the missing mass technique with the CMS-TOTEM precision proton spectrometer

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 mi...

description 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 $pp\rightarrow pp +{\rm Z}/\gamma+X$ are set, in the absence of significant resonant deviations in data with respect to the background predictions.
