 Single top quark production in CMS / Komm, Matthias (Imperial Coll., London) /CMS Collaboration Recent results on single top quark production are presented, using CMS data collected at different centre-of-mass energies. The single top quark analyses investigate separately the production of top quarks via t-channel exchange, in association with a W boson (tW) or via the s-channel.

 Observation of ${\rm t\bar{t}H}$ production at CMS / Diez, Carmen (DESY) /CMS Collaboration Recent searches for the production of a Higgs boson (H) in association with a top quark pair (${\rm t\bar{t}H}$) by the CMS Collaboration are presented. They are performed using 36 fb$^{-1}$ of LHC pp collision data at $\sqrt{s}$=13 TeV collected in 2016. [...] CMS-CR-2018-346.- Geneva : CERN, 2018 - 5 p.

 Monitoring tools for the CMS muon detector: present workflows and future automation / Calabria, Cesare (INFN, Bari ; Bari U.) /CMS Collaboration The CMS Muon System has been operated successfully during the two LHC runs allowing to collect a very high fraction of data with a quality that fulfils the requirements to be used for physics analysis. Nevertheless, the workflows used nowadays to operate and monitor the detector are rather expensive in terms of human resources. [...] CMS-CR-2018-275.- Geneva : CERN, 2018 - 9 p.

 The CMS-TOTEM Precision Proton Spectrometer and first physics results / Hollar, Jonathan (LIP, Lisbon) /CMS and TOTEM Collaborations Proton tagged photon-photon and gluon-gluon interactions represent a unique way to study the Standard Model, and to search for new physics beyond the Standard Model, in proton-proton collisions at the LHC. The CT-PPS project began operating near-beam detectors housed in Roman Pots during 2016, to detect the forward scattered protons in these processes. [...] CMS-CR-2018-248.- Geneva : CERN, 2018 - 5 p.

 Measurement and simulation of the background in the CMS muon detectors / Calabria, Cesare (INFN, Bari ; Bari U.) /CMS Collaboration The study of the different backgrounds which the muon detectors of the CMS experiment are exposed to, is fundamental to assess the system longevity and project its performance to the conditions expected for HL-LHC. In this respect, an accurate modelling of the backgrounds in simulation is of prime importance as many studies rely on simulation-based predictions while these future conditions have never been experienced in reality.

 CMS emittance scans for 2017 luminosity calibration / Tsrunchev, Peter (CERN) /CMS Collaboration Emittance scans are short van der Meer type scans performed at the beginning and at the end of LHC fills. The beams are scanned against each other in X and Y planes in 9 displacement steps and are used for LHC diagnostics and since 2017 for CMS luminosity calibration cross check.

 Forward energy flow and jet production in pp and pA collisions at the LHC with CMS / Van De Klundert, Merijn H F (DESY) /CMS Collaboration A measurement of inclusive differential cross sections for very forward jet production is presented as a function of jet energy in proton-lead collisions. These collisions were recorded with the CASTOR calorimeter of the CMS experiment at the LHC, which measures in the pseudorapidity range $-6.6<\eta<-5.2$.

 Van der Meer calibration of the CMS luminosity detectors in 2017 / Lujan, Paul Joseph (INFN, Padua) /CMS Collaboration Precision measurement of luminosity delivered by the LHC to the CMS experiment is a vital component of many physics analyses and important for optimal machine performance. In Run 2, the luminosity at CMS is measured by three online luminometers, the Pixel Luminosity Telescope (PLT), Fast Beam Conditions Monitor (BCM1F), and the hadronic forward calorimeter (HF), which provide high-precision real-time luminosity measurements.

 The Matrix Element Method used in the search for the associated production of the Higgs boson with top quarks and decaying into tau leptons / Zabi, Alexandre (Ecole Polytechnique) /CMS Collaboration Latest results of CMS searches for a Higgs boson produced in association with top quarks in final states with tau leptons are reported. This contribution will specifically focus on technical aspects related to the Matrix Element Method implementation and on its impact on the sensitivity of the analysis.

 Level-1 track finding with an all-FPGA system at CMS for the HL-LHC / James, Thomas Owen (Imperial Coll., London) /CMS Collaboration The CMS experiment at the LHC is designed to study a wide range of high energy physics phenomena. It employs a large all-silicon tracker within a 3.8 T magnetic solenoid, which in particular allows precise measurements of transverse momentum ($p_\mathrm{T}$) and vertex position.\\ This tracking detector will be upgraded to coincide with the installation of the High-Luminosity LHC, which will provide a luminosity up to about $7.5 \times 10^{34}\,\mathrm{cm^{-2}\,s^{-1}}$ to CMS, or 200 collisions per 25~ns bunch crossing.
