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|. [...]

Observation of proton-tagged, central (semi)exclusive production of high-mass lepton pairs in pp collisions at 13 TeV with the CMS-TOTEM precision proton spectrometer / CMS and TOTEM Collaboration
The process pp$\to\ell^+\ell^-$p$^{(*)}$, with $\ell^+\ell^-$ a muon or an electron pair produced at midrapidity with mass larger than 110 GeV, has been observed for the first time at the LHC in pp collisions at $\sqrt{s} =$ 13 TeV. One of the two scattered protons is measured in the CMS-TOTEM precision proton spectrometer (CT-PPS), which operated for the first time in 2016. [...]

First determination of the ${\rho }$ parameter at ${\sqrt{s} = 13}$ TeV: probing the existence of a colourless C-odd three-gluon compound state / TOTEM Collaboration
The TOTEM experiment at the LHC has performed the first measurement at √s = 13 TeV of the ρ parameter, the real to imaginary ratio of the nuclear elastic scattering amplitude at t = 0, obtaining the following results: ρ = 0.09 ± 0.01 and ρ = 0.10 ± 0.01, depending on different physics assumptions and mathematical modelling. The unprecedented precision of the ρ measurement, combined with the TOTEM total cross-section measurements in an energy range larger than 10TeV (from 2.76 to 13TeV), has implied the exclusion of all the models classified and published by COMPETE.

First measurement of elastic, inelastic and total cross-section at sqrt(s)= 13 TeV by TOTEM and overview of cross-section data at LHC energies / TOTEM Collaboration
The TOTEM collaboration has measured the proton-proton total cross section at $\sqrt{s}=13$ TeV with a luminosity-independent method. Using dedicated $\beta^{*}=90$ m beam optics, the Roman Pots were inserted very close to the beam. [...]

Characterisation of irradiated thin silicon sensors for the CMS phase II pixel upgrade / Adam, W (Vienna, OAW) ; Bergauer, T (Vienna, OAW) ; Brondolin, E (Vienna, OAW) ; Dragicevic, M (Vienna, OAW) ; Friedl, M (Vienna, OAW) ; Frühwirth, R (Vienna, OAW) ; Hoch, M (Vienna, OAW) ; Hrubec, J (Vienna, OAW) ; König, A (Vienna, OAW) ; Steininger, H (Vienna, OAW) et al. /Tracker Group
The high luminosity upgrade of the Large Hadron Collider, foreseen for 2026, necessitates the replacement of the CMS experiment’s silicon tracker. The innermost layer of the new pixel detector will be exposed to severe radiation, corresponding to a 1 MeV neutron equivalent fluence of up to $\Phi _{eq} = 2 \times 10^{16}$  cm$^{-2}$ , and an ionising dose of ${\approx } 5$  MGy after an integrated luminosity of 3000 fb$^{-1}$ .

A search for Higgs boson pair production in the $\mathrm{ b }\mathrm{ b }\tau\tau$ final state in proton-proton collisions at $\sqrt{s} = $ 8 TeV / CMS Collaboration
Results are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a $\tau$ lepton pair. This work is based on proton-proton collision data collected by the CMS experiment at $ \sqrt{s} = $ 8 TeV, corresponding to an integrated luminosity of 18.3 fb$^{-1}$. [...]

Exclusive and semi-exclusive $\pi^{+}\pi^{-}$ production in proton-proton collisions at $\sqrt{s} = $ 7 TeV / CMS Collaboration
A measurement is presented of the exclusive and semi-exclusive production of charged pion pairs in proton-proton collisions, $\mathrm{ p p }\to\mathrm{ p }({\mathrm{p}^*} )+ \pi^{+}\pi^{-}+ \mathrm{ p } ({\mathrm{p}^*} )$, where the $\pi^{+} \pi^{-}$ pair is emitted at central rapidities, and the scattered protons stay intact ($\mathrm{p}$) or diffractively dissociate (${\mathrm{p}^*} $) without detection.

A measurement is presented of the cross section for the electroweak production of a Z boson and a photon in association with two jets in proton-proton collisions at $ \sqrt{s} = $ 8 TeV. The Z bosons are identified through their decays to electron or muon pairs. [...]

Search for supersymmetry with multiple charged leptons in proton-proton collisions at $\sqrt{s}= $ 13 TeV / CMS Collaboration
Results are reported from a search for physics beyond-the-standard-model, such as supersymmetry, in final states with at least three charged leptons, in any combination of electrons or muons. The data sample corresponds to an integrated luminosity of 2.3 fb$^{-1}$ of proton-proton collisions at $\sqrt{ s} = $ 13 TeV, recorded by the CMS experiment at the LHC in 2015. [...]

Diamond Detectors for the TOTEM Timing Upgrade / TOTEM Collaboration
This paper describes the design and the performance of the timing detector developed by the TOTEM Collaboration for the Roman Pots (RPs) to measure the Time-Of-Flight (TOF) of the protons produced in central diffractive interactions at the LHC. The measurement of the TOF of the protons allows the determination of the longitudinal position of the proton interaction vertex and its association with one of the vertices reconstructed by the CMS detectors.
