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|. [...]

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. [...]

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.

Measurement of Elastic pp Scattering at $\sqrt{s}$ = 8 TeV in the Coulomb-Nuclear Interference Region – Determination of the $\rho$ Parameter and the Total Cross-Section / TOTEM collaboration
The TOTEM experiment at the CERN LHC has measured elastic proton-proton scattering at the centre-of-mass energy $\sqrt{s}$ = 8 TeV and four-momentum transfers squared, $|t|$, from $6\times10^{-4}$ GeV$^2$ to 0.2 GeV$^2$. Near the lower end of the $t$-interval the differential cross-section is sensitive to the interference between the hadronic and the electromagnetic scattering amplitudes. [...]

Evidence for Non-Exponential Elastic Proton-Proton Differential Cross-Section at Low |t| and $\sqrt{s}$ = 8 TeV by TOTEM / Antchev, G. (Sofiya, Inst. Nucl. Res.) ; Aspell, P. (CERN) ; Atanassov, I.

(CERN) ; Bottigli, U. (INFN, Siena ; U. Siena (main)) ; Bozzo, M. (Genoa U. ; INFN, Genoa) et al.
The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy $\sqrt{s}$ = 8TeV based on a high-statistics data sample obtained with the $\beta$* = 90m optics. Both the statistical and systematic uncertainties remain below 1%, except for the t-independent contribution from the overall normalisation. [...]
