A search for new physics in central exclusive production using the missing mass technique with the CMS detector and the CMS-TOTEM precision proton spectrometer
A generic search is presented for the associated production of a Z boson or a photon with an additional unspecified massive particle X, $ \mathrm{p}\mathrm{p}\to \mathrm{p}\mathrm{p} +\mathrm{Z}/\gamma+\mathrm{X} $, in proton-tagged events from proton-proton collisions at $ \sqrt{s}= $ 13 TeV, recorded in 2017 with the CMS detector and the CMS-TOTEM precision proton spectrometer.

Search for high-mass exclusive $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
A search is performed for exclusive high-mass $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $ \sqrt{s}= $ 13 TeV, corresponding to an integrated luminosity of 100 fb$ ^{-1} $. [...]

Proton reconstruction with the CMS-TOTEM Precision Proton Spectrometer / CMS and TOTEM Collaboration
The Precision Proton Spectrometer (PPS) of the CMS and TOTEM experiments collected 107.7 fb$ ^{-1} $ in proton-proton (pp) collisions at the LHC at 13 TeV (Run 2). This paper describes the key features of the PPS alignment and optics calibrations, the proton reconstruction procedure, as well as the detector efficiency and the performance of the PPS simulation.

Characterisation of the dip-bump structure observed in proton–proton elastic scattering at $\sqrt{s}$ = 8 TeV / TOTEM Collaboration
The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton-proton scattering at $\sqrt{s} = 8\ {\rm TeV}$ in the squared four-momentum transfer range $0.2\ {\rm GeV^{2}} < |t| < 1.9\ {\rm GeV^{2}}$. This interval includes the structure with a diffractive minimum ("dip") and a secondary maximum ("bump") that has also been observed at all other LHC energies, where measurements were made. [...]

First search for exclusive diphoton production at high mass with tagged protons in proton-proton collisions at $\sqrt{s} =$ 13 TeV / CMS Collaboration
A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp $\to$ p$\gamma\gamma$p with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb$^{-1}$ collected in 2016 using the CMS and TOTEM detectors at a center-of-mass energy of 13 TeV at the LHC. [...]

Hard color-singlet exchange in dijet events in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS and TOTEM Collaboration
Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at $\sqrt{s} = $ 13 TeV. The signature is expected from hard color-singlet exchange. [...]

Comparison of pp and pp ̄ differential elastic cross sections and observation of the exchange of a colorless C-odd gluonic compound / V.M.~Abazov, V.M. (-) ; Abbott, B. (-) ; Acharya, B. S. (-) ; Adams, M. (-) ; Adams, T. (-) ; Agnew, J. P. (-) ; Alexeev, G. D. (-) ; Alkhazov, G. (-) ; Alton, A. (-) ; Antchev, G. (-) et al.
We describe a quantitative analysis comparing the p anti-p elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a mainly model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of sqrt(s) = 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section.

Measurement of single-diffractive dijet production in proton-proton collisions at $\sqrt{s} =$ 8 TeV with the CMS and TOTEM experiments / CMS and TOTEM Collaborations
Measurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum loss $\xi$ and the four-momentum transfer squared $t$. Both processes ${\mathrm{p}}{\mathrm{p}} \to {\mathrm{p}}\mathrm{X}$ and ${\mathrm{p}}{\mathrm{p}} \to \mathrm{X}{\mathrm{p}}$, ie with the proton scattering to either side of the interaction point, are measured, where $\mathrm{X}$ includes at least two jets; the results of the two processes are averaged [...]

Elastic differential cross-section ${\rm d}\sigma/{\rm d}t$ at $\sqrt{s}=$2.76 TeV and implications on the existence of a colourless 3-gluon bound state / TOTEM Collaboration
The proton-proton elastic differential cross section dσ /dt has been measured by the TOTEM exper- iment at √s = 2.76 TeV energy with Beta∗ = 11 m beam optics. The Roman Pots were inserted to 13 times the transverse beam size from the beam, which allowed to measure the differential cross- section of elastic scattering in a range of the squared four-momentum transfer (|t|) from 0.36 GeV2 to 0.74 GeV2.

Elastic differential cross-section measurement at $\sqrt{s}=13$  TeV by TOTEM / TOTEM Collaboration
The TOTEM collaboration has measured the elastic proton-proton differential cross section dσ/dt at √s = 13 TeV LHC energy using dedicated beta∗ = 90 m beam optics. The Roman Pot detectors were inserted to 10σ distance from the LHC beam, which allowed the measurement of the range [0.04 GeV**2;4 GeV**2] in four-momentum transfer squared |t|. [...]
